OK - foolish me. My iPhone 4, which I am keeping at 6.1.3 popped up with the 7.0.2 release message. I thought woohoo! And pressed update. Aarrgh! No! There appears to be no way to stop the update process, other than starting from scratch with my phone. I turned off wifi and made an itunes backup and reset. Then tried to restore from an earlier icloud backup. The icloud restore fails. If I restore from the itunes backup, the 7.0.2 OTA update starts up again! I didn't notice this and it has now got as far as "preparing upgrade". The only way to stop this seems to be to reset the phone. :-( Does anyone have a clue how I can restore my backup, while avoiding the update? My patience with Apple is wearing thin right now! Update: i managed to save my 6.1.3 intallation by applying a semi-tethered redsnow jailbreak. This cancelled the OTA and allowed me to install Cydia patches to disable OTA updates.
