As it’s been promised, the awesome folks from iPhone DevTeam have finally released the long anticipated software unlock hack for the iPhone 3G. Dubbed “Yellowsn0w”, this iPhone 3G unlock hack is completely free to download and install.

Currently in beta (v0.9.1) stage, Yellowsn0w comes in the form of a native program for the iPhone that needs to be installed and run on the device in order to unlock the iPhone 3G. This unlock software works exclusively with baseband 02.28.00 that is provided by the latest iPhone firmware update (v2.2) from Apple. You’ll need to upgrade to this firmware using iTunes and then use QuickPwn to activate and jailbreak the device.

Afterwards, one can download Yellowsn0w through either Cydia or Installer.app, by adding the following repositories: http://apt9.yellowsn0w.com (Cydia) or http://i.yellowsn0w.com (Installer.app).

iNSTALLATION iNSTRUCTIONS:
1. Install yellowsn0w
2. Reset ALL Settings
3. Reboot your iphone
4. Wait a little over a minute
5. Remove your sim card and re-insert it back in
6. Wait 30 seconds
7. Turn on Airplane mode and wait 10 sec.
8. Turn off Airplane mode
9. Eject the sim tray and reinsert it back.

IMPORTANT NOTES:

- There is a known issue with SIM cards that have STK (SIM Toolkit) application menus. These menus are usually items such as “top up” “get credit” “lotto numbers” etc. These menu items confuse the application sometimes. Removing and reinserting the SIM once after reboot (give it about 10 secs 60 seconds (with v0.9.1) after you see the slide to unlock widget) fixes this issue.
- If you are in the U.S. and are trying this with T-Mobile, you must turn off the 3G switch in Settings. Also if you are good with the command line, you can make it much easier by adding the line -q right after the /usr/bin/yellowsn0w line in /System/Library/LaunchDaemons/org.iphone-dev.yellowsn0w.plist.
- No PIN support yet. Please disable any PIN you may have on that SIM before trying yellowsn0w, for now.
- The unlock will silently quit on anything other than baseband 02.28.00. It detects the wrong version and just quits to avoid any damage. Please double check your Modem Firmware setting in Settings->General->About.
