Nokia n73 I think it's not bad at all. because it has 3D good sound, 3 mpg camera (outdoor quality is the best of all, you can set up as if it is a digital cammera) , video MP4. But maybe it is a little bit to slow

Customize your Ringtones for all types of phone by yourself

Well, if you love to modify your phone ringtones, here I got links for sound finder, you can search your favorites sound (wav) and then export it using your software tools like pc suite, sound composer, etc.

You can use this links : http://www.findsounds.com/ISAPI/search.dll?keywords= <-your keyword here->

For example, you want to find the sound of duck , you can use : http://www.findsounds.com/ISAPI/search.dll?keywords=duck

If you don’t have any idea what kind of sound for your ringtones you can see the lists here

Have a nice ringtones :D

Can you hear these ultrasonic ringtones?

I found this from stumbleupon, source : Can I hear these ultrasonic ringtones?

As far i could hear, just 16, 7 khz, of course my age is more than 20.

Find out just how far your ears can hear into the range of ultrasonic ringtones. Pretty much everyone should be able to hear the lowest tone (8kHz). Many people should be able to hear up to around 14.1kHz, from around 17kHz upwards we get into the range that only the under 20's can hear!

	8kHz		Download 8kHz tone

How to modify your K800i appearance

source : http://forums.se-nse.net/index.php?showtopic=5797

You can use a modified phoneXC, as discused in Research & Development, you can access any filesystem with brute forcing... (but it takes time... he has to wait up to 5h to get the files uploaded)

Removing camer shutter sounds
That's an easy trick. There are 4 different shutter sounds you can choose from (in the camera software).
If you want to delete one of them, for example sound nb. 4, just delete the files:

CODE

/tpa/preset/system/sound/camerashutter4.3gp
/tpa/preset/system/sound/camerashutter4_rer.3gp

and it will be gone!


Replacing reminder sound (calendar)Replace

CODE

/tpa/preset/system/sound/REMINDER.3GP

with a .3gp sound file of your choice


Replacing the splash screen with a custum one
It's the same as with the K750 - you have to replace

CODE

/tpa/preset/system/settings/splash

But you'll need 240 (width) x 320 (height) images.
I've converted the splash screen by Alete to this size. It's attached to this post (splash_modded.zip)


Replacing startup/shutdown clips with W850 startup/shutdown clips
Again it's the same as with the K750, files that have to be replaced are:

CODE

/tpa/preset/system/settings/STARTUP_IMAGE_SEMC
/tpa/preset/system/settings/SHUTDOWN_IMAGE_SEMC

Replacing the main menu
Nothing has changed here, too, but you'll need bigger images.

QUOTE(oblivion @ 2006-11-18 11:27)

The size for K800 icons is:
unselected : 73x53px
selectes : 91x69px

I've already converted 2 menu's to the K800 menu.ml:
-> the luix theme by pixelboy (attached as luix_K800.zip to this post):

as you can see, the images are a bit small as the menu was designed for a K750 with smaller images.


-> the tux theme by macgywer (attached as tux_K800.zip to this post):


This theme fits the K800 perfectly, as I've made the icons bigger (they have now a width of 240pixels)

Replacing the media player skin
UPDATED
That's possible BUT, using media player skins for K750 is not possible, atm I'm trying W850 skins.

Changing the font
I was able to replace the Sans-Serif font with another, but sadly the font didn't work... So it is possible, but you need fonts that work with the K800.. At the moment I don't have such fonts.


Modding the camera driver
It's possible to raise the jpeg quality, but as the standard quality setting for 3MP images (with the setting "fine") is already set to 90, it doesn't make a big difference.

The interesting part is the resolution & the framerate of the recorded videos... Though it looks like the camera can deliver a 320x240@10fps video, I wasn't able to change the camera driver in order to record at that quality... Even raising the framerate of the standard resolution makes the camera software crash....
-> I gues that changing these things is not possible without pacthing the firmware

Nokia N95 Tips : review on N95

Well, i've been surfing arround about why we have to choose N95 intead of others hanphone, well you can see on ukOnline
===================
This page is for anyone thinking of migrating to the Nokia N95 with a view to using it as their main communicator and entertainment device

The N95 has lots to recommend it, from the 5 megapixel stills camera and VGA video capture at 30fps to the built-in GPS, stereo speakers and standard 3.5mm audio out. There's also the very latest Symbian OS and S60 versions, with multimedia functionality thrown in by the bucketload.

1. Ignore those 'Exit' buttons? Err... not necessarily!
   Unlike some other previous S60 smartphones (e.g. the N70), the N95's RAM is rather more limited (does the error message 'Memory full' ring any bells? Yep, thought it would). Starting with 21MB free, you'll usually be running with just over 13MB free, even in optimal conditions. You can still have many of your S60 apps running at the same time, which means no delays while applications are launched/switched to, with the usual trick being to ignore those 'Exit' buttons. When you need to switch to a different application, press the Menu ('Applications') button and select it from there, leaving the current app running.
   However: don't do this for Camera, Gallery, Web, Java games or the built-in Maps, any of which can hog RAM and cause your other main programs to close down gracefully in the background. For each of these RAM hogs, DO use 'Exit' for these programs, after use, to make sure RAM is freed up. In particular, make sure to manually 'Exit' Camera (or close the physical shutter) after using it every single time, if you want to avoid problems.
   
   
   
2. Auto-startup? Say no!
   In the battle to have as much free RAM as possible, it's important to avoid any applications or utilities that try to auto-start on your N95 and hang around in RAM. A good example is Nokia's Wireless Keyboard utility, which works brilliantly to connect you to a Bluetooth keyboard but then defaults to staying loaded in RAM at all times, using up to 2MB on its own. Switch to it and alter its Settings to turn this behaviour off and then 'Exit' it manually. You know it makes sense.
   Several third party 'helper' utilities try to do the same thing, e.g. Epocware's Handy Weather. Best avoided if you value your RAM.
   
   
3. Firmware, firmware
   It's vital to stay up to date in terms of N95 firmware, i.e. the software inside the smartphone. Now, this isn't trivial, as it involves (at best) backing up your N95, running the Nokia Software Updater and having the internal disk of the device completely wiped and relaid, followed by restoring your data, but with the N95 being quite cutting edge you should take advantage of all the bug fixes you possibly can!
   
   
   In particular, v12 firmware gives you better RAM management and Assisted GPS (lock times of 10 seconds or so!!)
4. Far too sharp?
   There's a big bug in the v10 and v11 N95 firmwares that you need to be aware of. When started, Camera's default 'Sharpness' setting is 'Normal'. But change ANY of the 'scene modes' (e.g. 'Close-up') and 'Sharpness' gets set to 'High'. To use the N95's camera in a scene mode, remember to also go down to the bottom of the camera control icons and reset the 'Sharpness', otherwise your pictures are going to end up effectively unusable!
   This has been fixed in the new v12 firmware, so upgrade via Nokia Software Update (see above) or pester your network operator/service centre, etc.
   
   
5. Downgrade that camera
   Now, this is going to seem like heresy, but do you actually need a 5 megapixel camera? Each image will take up well over a megabyte on your memory card. For most purposes, perhaps printing photos at 7" by 5" or viewing on a TV, 3 megapixel images are absolutely fine - why waste precious space if you don't have to? You can lower the camera resolution by opening the camera and using its 'Settings'.
   
   
   
6. Faster photos
   One stat that's not loved much about the N95 is the shot-to-shot time of its stills camera. This is mainly because the default setting for 'Show captured image' is 'On'. Loading and decoding a megabyte plus of JPG does take a while - do yourself a favour - if you can live without display of what you've just snapped, turn this setting 'Off' and you'll be able to snap photos only three seconds apart, much quicker than the default!
   
   
7. Preserving battery life
   You'll have gathered by now that the Nokia N95's battery is a little on the slim side, considering the amount of high-tech goodies it's got to power. Here are a few tips to last longer on your daily charge:
   
   • Firstly, make damn sure you do charge the N95 each night, so at least it's starting the day on 'full'
   • The Camera is the single biggest power drain. While waiting to take shots or shoot a video clip, don't keep the camera with a 'live' viewfinder - better to close it down and then open it again just before you actually need to take the shot/clip. And if you're going to an event where you know you'll be using the camera/camcorder a lot, consider taking along a spare battery or portable charger
   • Keep WLAN scanning off, you can always scan manually if needed, or turn it back on
   • Unless you know you're going to be staying in an area with good 3G signal and you know you have a 3G SIM card, go into 'Tools | Settings | Phone | Network' and change 'Network mode' to 'GSM' - this will stop the N95 hunting for 3G signals, expending large amounts of power switching cells and holding on to weak mast locks.
   • Watch what applications you leave running in the background - some games and Java applications are especially processor hungry, even when paused!
   • When using the N95 as a navigator in car, with display and GPS both active, do yourself a favour and buy a $10 12V adapter/charger, so that instead of draining the battery at a rate of knots you're actually gaining extra charge.
   
   
   
8. Camcorder tips
   The VGA video capture is one of the unique selling points of the N95, so make sure you make the most of it.
   • Make sure you use a top-spec, high performance microSD card. At 28MB/min you're going to need it. A SanDisk Ultra II is ideal. Don't buy a cheap copy off eBay, get one from a genuine vendor.
   • Don't use digital zoom - you're simply throwing away quality. If you need to get closer to your subject then get closer!
   • Don't try and film too close to the N95, as there's no auto-focus in video mode. Stick to subjects more than a metre away.
   • As with still photos, film only in good light; you'll be very disappointed by anything shot in dim conditions.
   • Don't pan around a scene too fast. Despite the spec of shooting at 30fps, the N95's video will appear slightly jerky.
   
   
   
9. Making DVDs and videos
   Nokia bundle a version of Adobe Premiere Elements 2.0 with the N95 - ignore it, unless you happen to have a twin-processor monster of a PC. As usual, Adobe's software is incredibly inefficient and you'll struggle on a normal computer. In addition, it doesn't seem to like the N95's VGA video files very much and I had lots of problems. Ditto with the simplistic Apple Quicktime Pro. Instead, head over to ulead.com and get the full version of VideoStudio 10 Plus, which, when patched to the latest service pack, does an excellent job of handling N95 video files and rendering them to DVD or other video formats.
   
   
   
10. The ones you love the most
    With the Nokia N95, there's S60's usual 'active' standby screen. Don't just take the shortcuts given, I'm sure you have ideas of your own as to your most used applications. You can change any of the six shortcuts in the rather-hidden-away 'Tools | Settings | General | Personalisation | Standby mode | Active standby apps' (Phew, you really have to get to know the settings hierarchy on these devices!)
    
    
11. A cleaner, clearer standby screen
    You can do a lot to make your active standby screen brighter, cleaner and more useful. See my tutorial over on AllAboutSymbian (though note that some of the Settings menu paths are slightly different - don't worry, you'll work it out).
    
    
12. Calendar shortcuts
    In Calendar, '#' moves you immediately to the current day, while '*' toggles between the different views. And if you need to start a new 'meeting' entry at any point, just start entering text...
    
    
13. The latest and best (1)
    Make sure you keep up to date with PC Suite. Yes, there's a version on the CD that came with your smartphone, but Nokia are fixing bugs and adding bits and pieces all the time. Most useful is the way you can explore your smartphone's folders (including your text Inbox) from within Windows Explorer. Very cool. Keep an eye on the PC Suite home page and stay current!
    
    
14. Quick music
    Never mind the pretty but very slow 'multimedia menu' - you can go straight to music player by pressing and holding the multimedia key.
    
    
15. Pump up the brightness
    Consider increasing the screen from the default brightness to its maximum. Yes, there's a hit on the time between battery recharges, but in the meantime you'll see some glorious colours. Go to 'Tools | Settings | General | Personalisation | Display | Light sensor' and adjust away. At night-time, if you're actually reading from the screen, you can use the same setting to turn the brightness right down to save being dazzled.
    
    
16. Hangup = Exit
    Don't keep switching back to the Standby screen using the Hangup button. This was OK on old versions of S60, but in almost every instance it closes the current application on the N95 - in other words, it acts as 'Exit'. If you want to keep the current program running in the background, press Menu/Apps instead, twice if you want to get to Standby screen.
    
    
17. What's running?
    The one utility every computer user needs is a system task manager (i.e. what's running). Luckily, the basics are built-in. Just press and hold the 'Menu/Applications' button. For more control, grab the trial version of Best TaskMan.
    
    
18. The ones you love the most (2)
    If you get fed up scrolling down the Menu screen lookng for your favourite applications again, why not shuffle things round so that the apps you use the most are clustered right at the top? Highlight an icon and use 'Move', and you'll find you can re-insert it anywhere in the list. If you have lots of favourites, make the most of the folder system (e.g. 'Games') and then put these folders near the top of the list, for speedy access.
    
    
19. Switching to landscape
    Perhaps an obvious tip, perhaps not, but you can run any application in 'landscape mode' by simply opening the music slide - this can be quite handy for apps like Web and Gallery. It's also well worth noting that Web can be run in 'Rotated' mode by using the appropropriate menu option with the keypad open, giving you the best of both worlds, i.e. landscape web browsing and text input when needed!
    
    
20. Quicker removal
    In the previous tip, you'll have noticed that App Mgr is a very slow application - don't use it to remove applications from your N95. A much quicker way is simply to highlight the program you want to zap and press the 'C' key. Cool, eh?
    
    
21. The ones you love the most (3)
    The N95 displays 12 application icons on a menu screen at any moment, as do most other S60 phones. The numeric keypad also has 12 buttons. You can select menu icons by pressing the keypad button that corresponds to the location of the application item on the screen. So '1' activates the topmost left application and so on.
22. Open up your device
    By default, the N95 may (depending on your operator) come 'locked down' in terms of the applications it'll accept, installing only those that have large companies behind them, able to afford the expensive 'signing' process. But there are hundreds of other great applications, many of them free, that are 'unsigned' (although under S60 3rd Edition, totally unsigned applications are heavily restricted in what they can do). Don't worry about this (see my malware article to put your mind at rest). Just go to 'Tools | App manager | Options | Settings' and set 'Software installation' to "All". and 'Online certif check' to "Off". You can now install any compatible program without being blocked by spurious security warnings!

Comparison using mini opera 3.x vs default opera 8.6x web browser for symbian uiq 3.

Actually I use sony ericcson m600i, and it has default opera web browser. A friend said to me that we can use mini opera. Well if your constraints is a cheaper cost, low bandwith,less phone resource I think this mini opera is match for you. It is an midp java application, you can install it to every phone that support java application, such as p990, w850

How it works?
Actually when you access a web page, mini opera contact their server and the server compress the destination web page, and then send it to your phone. That's why it has slower speed but less KBytes transfered. You can save kbytes until 4-five times smaller

When you use the opera 8.6x, you will feel faster speed, because of no compression. You can play online music or event video streaming from youtube.com, but ofcourse it need greater resource.

I usually use mini opera when i have to pay every kbytes data transfered.and now I use mobile network that allow unlimited data transfered, so goodby mini opera :D

Nokia Secret Codes

source : http://nokiatone.ifrance.com/nokiatone/secrets.htm
I think it's worth to try

To check the IMEI (International Mobile Equipment Identity) Type-

*#06#

Information you get from the IMEI-

XXXXXX XX XXXXXX X

TAC FAC SNR SP

• TAC = Type approval code

• FAC = Final assembly code

• SNR = Serial number

• SP = Spare

To check the phones Software revision type-

*#0000#

Information you get from the Software revision-

V 05.31

18-02-99

NSE-3

• 1ST Line = Software revision

• 2ND Line = The date of the software release

• 3RD Line = Phone type

To enter the service menu type-

*#92702689# (*#WAR0ANTY#)

• Serial number (IMEI)

• Production date (MM/YY)

• Purchase date (MM/YY) You can only enter the date once.

• Date of last repair (0000=No repair)

• Transfer user data to another Nokia phone via Infra-Red

Clock Stopping

To check weather your SIM Card supports clock stopping type-

*#746025625# (*#SIM0CLOCK#)

Revealing the Headphone and Car-Kit menus

Please note that if you do these next tricks, the new menus can't be erased without retoring the factory default settings. To do these tricks you need to short-circuit the pins on the bottom of the phone next to where you plug in you charger.

1. To activate the "Headset" menu, you need to short-circuit pins "3" and "4". After a short time the word "Headset" will be shown in the display. Menu 3-6 is now enabled.

2. To activate the "Car" menu, you need to short-circuit pins "4" and "5". After a short time the word "Car" will be shown in the display. Menu 3-7 is now enabled.

THE REBOOT TRICK

This should work on all software versions of the 6110.

1. Go to the Calendar (Menu-8)

2. Make a note or reminder.

3. Enter some text into the edit box.

4. Hold "Clear" until the whole text is cleared, then press "Back".

5. Press "0". The main screen will now be showing but a space appears on the screen. (you can't see it)

6. Enter 4 digits (e.g. 1234).

7. Use the down arrow to move the cursor to the left side of the numbers and the space (Down arrow twice).

8. Now enter 6 digits and press the call button.

Wait for a few seconds, the screen should start to flash and reboots. It should alsowork on other menus like the "Profiles" menu.

EFR CALL QUALITY

To activate EFR (Enhanced Full Rate) Enter the code-

*3370#

This improves call quality but decreases batterylife by about 5%

To deactivate it, Enter the code-

#3370#

THE JAMES BOND TRICK

If you short-circuit theleft middle and right pins on the bottom of the phone with all connections touching each other, the Nokia software hangs! The profile "Headset" will be activated. Before you do this just activate the "Automatic Answer" in the headset profile and set the ringing volume to "Mute". Now you can use your phone for checking out what people are talking about in a room. Just place it under a table in a room and call it. The phone receives the call without ringing and you can listen to what people are saying.

NETWORK MONITOR

There is a hidden menu inside your Nokia phone. If you want to activate it, you'll have to re-program some chips inside of your phone.

1. Check your software version. You can only continue if you have v4.33, v4.73 or v5.24.

2. Take apart the phone.

3. De-solder the EEPROM (ATMEL AT 24C64).

4. Read out the data with an EEPROM programmer and save it to a file (Backup).

5. If you have v.33 or v4.73, change the address "03B8" from "00" to "FF".

6. If you have v5.24 then change the address "0378" from "00" to "FF".

7. Write the new data to the EEPROM and solder it back to the phone,

8. Power on your phone and you should have "Netmonitor" enabled.

The Network Monitor gives you the following information.

• Carrier number

• MS RX Level in DBM

• Received signal quality

• MS TX power level

• C1 (Path loss criterion, used for cell selection and reselection). The range is -99 to 99.

• RTL (Radio link timeout).

• Timeslot

• Indication of the transmitter status

• Information on the Network parameters.

• TMSI (Temporary Mobile Subscriber Identity).

• Cell identification (Cell ID, Number of cells being used).

• MCC (Mobile country code)

• MCN (Mobile network code)

• LAC (Location area code)

• Ciphering (On/Off)

• Hopping (On/Off)

• DTX (On/Off)

• Discard cell barred information

CHECK SIM-LOCK

Note - If you bought your Nokia on UK Vodafone or UK Cellnet you do not need to check this because they both transmit on GSM900, and they don't lock the phones. However if you bought your phone on UK Orange or UK One2one your phone may be blocked. The reason is that they both transmitt on GSM1800. To make a call on GSM1800 you need what is known as a "Dual band" phone. A dual band phone is able to transmit on both GSM900 and GSM180

Download youtube videos on computer and handphones/PDAs

Well, I wonder, whether I can download youtube or not. When I did googling, there are thousands of site that i can download youtube.
Here some site that you can use to download youtube videos :
1. Kissyoutube.com
all you need to do is just add the word "kiss" to the address, for example :
http://www.youtube.com/watch?v=yJTwT2bJhrg
become
http://www.kissyoutube.com/watch?v=yJTwT2bJhrg

2. if you use hanpdhones/pdas, you can use Tinytube
Actually there are so many post about this, but when I was surfing with my sony ericcson M600i, I can't download it, maybe somebody can help me. By the way when I use the M600i default browser, I found that this phone can play direcly to youtube.com without connecting tinytube. Unfortunately my connection speed is too low so that i can't see it clearly

3. Just using Your Browser
well, all you need is download the link to a file, and then just rename it using file FLV

Tunneling lesson, what is tunneling and how to create it

ssh.com
Tunneling, or port forwarding, is a way to forward otherwise insecure TCP traffic through an encrypted Secure Shell tunnel. You can secure for example POP3, SMTP and HTTP connections that would otherwise be insecure.

Note: The client-server applications using the tunnel will carry out their own authentication procedures (if any) the same way they would without the encrypted tunnel.
The tunneling capability of SSH Secure Shell for Workstations is a feature that allows, for example, company employees to access their email, company intraweb pages and shared files securely by even when working from home or on the road.

Tunneling makes it possible to access email from any type of Internet service (whether accessed via modem, a DSL line or a cable connection, or a hotel Internet service). As long as the user has an IP connection to the Internet she can get her mail and access other resources from anywhere in the world securely.

This often is not the case with more traditional IPSec based VPN technologies because of issues with traversing networks that are implementing Network Address Translation (NAT) - this is especially the case in hotels. NAT breaks an IPSec connection unless special protocols such as NAT-Traversal are implemented on the client and gateway.

The client-server applications using the tunnel will carry out their own authentication procedures, if any, the same way they would without the encrypted tunnel.

The protocol/application might only be able to connect to a fixed port number ( e.g. IMAP 143). Otherwise any available port can be chosen for port forwarding.

Local And Remote Forwarding

There are two kinds of port forwarding: local and remote forwarding. They are also called outgoing and incoming tunnels, respectively.

Local port forwarding forwards traffic coming to a local port to a specified remote port. For example, all traffic coming to port 1234 on the client could be forwarded to port 23 on the server (host).

Note: The value of localhost is resolved after the Secure Shell connection has been established - so when defining local forwarding (outgoing tunnels), localhost refers to the server (remote host computer) you have connected to.

Remote port forwarding does the opposite: it forwards traffic coming to a remote port to a specified local port. For example, all traffic coming to port 1234 on the server (host) could be forwarded to port 23 on the client (localhost).

The tools that we need make a tunnel by using remote termal client such as http://www.vandyke.com/products/securecrt/ or putty
by visiting there you are also get an information how to do tunneling
