OK I updated my iPhone to the new 1.2 version today. But I don't have an o2 sim card so obviously it wanted me to activate it. I thought ZiPhone would jailbreak it for me so I used that and now but it didn't work, it just made my iPhone into a brick. And when I tried to get it back to the 1.1.4 version of the firmware I get this error: 'The iPhone "iPhone" could not be restored. An unknown error occurred (20).' Any chance I can get it back working? Or have a messed with it so I can't now restore it? : ( Any help would be very much appreciated!
