Hey guys...i have an iPhone 3g 16gb that was unlocked to use any carrier with version 2.2....I updated to 3.0 but then my iPhone keeps on saying connect to iTunes....showing the cable connecting to the iTunes cd on the screen. When i connect it to iTunes....it says " The sim card inserted in this iPhone does not appear to be supported, Only compatible sim cards can be used to activate the iPhone. Which means it's askin for an AT&T sim card which i don't have. Is there anyway to activate the iPhone so i can get to the home screen on the iPhone? And a question for those who have updated to 3.0...did you guys use an At&t sim card to activate or did you use any other methods of activating?
