Thx for the info, u should add the information that o2 uk will unlock only iphone 1Gen 3G and 3GS only. not iphone 4, at least for now.

Hi,

i have a 3GS with Firmware 3.1.2. baseband is 05.11.07 and used blackra1n to jailbreak. I need blackra1n to startup everytime.

So can i use pwnage tool to jailbreak and unlock my phone with iOS4?

Many thanks for your help and many thanks to the dev team for their work
