2009 arrives with good news for the thousands of iphone 3G users who want to travel with their phones to other countries and do not want to pay millions for roaming charges.

The dev-team (those that publish software to Jailbreak the phone) are about to launch yellowsn0w which is an application with which you can unlock a 3G iPhone, that means you can put any SIM of any company in the world and use it.

Yellowsn0wis the world’s first software unlock for the iPhone 3G. With yellowsn0w you can unlock your iPhone 3G firmware 2.2 and use it with any other carriers apart from AT&T

Before Downloading this application, DEV team want’s you to read some important recommendations:

  • The application works only with the recent  BASEband(02.28.00), therefore it is necessary to upgrade to the latest firmware (2.2) and then activate it using Jailbreak QuickPwn.
  • It will be possible to add the application using Cydia and other sources of shock.
  • The dev-team emphasizes that yellowsn0w is available with a non-commercial license, i.e prohibiting sale or charge for it.

How to Upgrade to iPhone 3G Firmware 2.2 with baseband 02.28.0

1. Download iPhone 3g Firmware 2.2

2. Jailbreak iPhone 3G Firmware 2.2 Using QuickPWN 2.2 and add Cydia/Installer.

Note: After you install yellowsn0w via Cydia, you should return to the Cydia main menu then reboot your iPhone with the 3rd party SIM installed. Wait for the slide to unlock screen, then wait 10 or 15 secs more. If you don’t see your carrier name pop up, then remove your SIM, reinsert it, and wait 10 secs more.(The DevTeam plans on elimintating this step)

Yellowsn0w is also easily uninstallable and completely removable through Cydia, the command line, or iTunes. Yellowsn0w currently is in beta phase with version 0.9, so use it at your  own risk.
