George Hotz, the man who performed the first successful iPhone unlock, has just released a full software unlock for iPhones running versions 1.1.2 and 1.1.3 of the firmware. According to iPhone Alley, newer iPhone models sold arrived with a new bootloader which kept current unlocking methods from working. The new method seems to work around this and allows users to use the iPhone with unapproved wireless carriers.

Full instructions can be found on Hotz's blog and consist of the following steps:

1. Download the gunlock and the secpack files from http://iphonejtag.blogspot.com/ or the blog. :-) Users can find the 4.02.13 files from http://george.zjlotto.com/index.php/baseband/.

2. Downgrade your phone to 1.0.2. See all the great tutorials online to do this. Your baseband won't be downgraded, this is normal. This will probably work on other versions too, but 1.0.2 doesn't lose WiFi access.

3. Kill CommCenter and run "gunlock secpack ICE04.02.13_G.fls"

4. Reload CommCenter. For some reason my phone was in brick mode. Use the elite team bricktool to get out.

5. Enjoy your 1.1.2 OTB unlocked iPhone.

It's not entirely for the tech faint-of heart and won't make Apple happy where your warranty is concerned, but there it is.
