I just picked up my third iphone (vibrate broke on first, dropped second). How do I know what firmware I have for sure. I do the *3001.......trick, and my firmware version is 04.03.13_G. According to the serial I am week 52. It seems like that week was the transition from 1.1.2 to 1.1.3.
Any help is good. If I have 1.1.2 at least I have an ipod touch for now.
