The iPhone Dev Team has just released the world’s first iPhone 3G Software unlock.

You must be upgraded to the 2.2 Baseband (2.28.00) in order to use the unlock. The application is a small daemon that is launched on boot and also whenever there is a baseband reset, you won’t know anything about it (apart from the use of the third-party SIM) it is small and unobtrusive, there is no GUI, this is by design.

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” etc. These menu items confuse the application sometimes, removing and reinserting the SIM fixes this issue.

For those of you using SIM cards without STK menus, the application has some optional arguments that will make the unlock much faster for you. So either experiment on your own (use “yellowsn0w -h” for usage) or wait for a customization writeup.

To perform the unlock you must install the yellowsn0w package from one of the following sources:
- Cydia source: http://apt9.yellowsn0w.com/
- Installer repo: http://i.yellowsn0w.com/

We are currently writing a tutorial for the iPhone 3G unlock and will post it shortly.

Stay Tuned!
