iPhone 1.1.3 unlock and jailbreak
Well, “iphone.unlock.no”:http://iphone.unlock.no seems to have the best advice for what to do and it is a great FAQ. In short:
# If you have 1.1.2 unlocked and jailbroken, then there is now an official 1.1.3 jailbreak. You don’t need to re-unlock since 1.1.3 didn’t change the baseband firmware. Main thing is _DO NOT USE ITUNES_ to upgrade to 1.1.3
# You can now downgrade the pesky bootloader in an out of the box 1.1.2 (that is V4.6 bootloader) to a more amenable version 3 bootloader. Unfortunately, you have to disassemble your phone and touch some “test points” on the motherboard, so it is not for the faint of heart!
# If you have an unlocked 1.0.2 phone or have a bricked 1.1.1 phone (IMEI is 0049) then you need to repair the phone by virginizing it. This is now easy, you just add _http://i.unlock.no_ as a Source in the Installer.app on your iphone, then make sure BSD Subsystem is installed from the System category and The Virginizer is installed in the Unlocking Tools category.
As an aside, the very best iphone hacking sources seem to me to be:
