Hi , looking for some help . I have an iphone which was unlocked to version 1.1.4 . i am wanting to update it to the latest softwear , i am in the UK and i am on 02 . I have a mate who is with 02 and has updated it everytime without it blocking his phone .

So question is , if you are on an o2 sim do you have to unlock it ? if i update will it stop my sim from working ?

cheers
Stuart

Try searching & reading the stickies.

You can try WinPwn 2.5 Beta 2 and that's it
