THE MAC DOC When I attempted to apply the 3.1 firmware update, it completely screwed my iPhone. And I do mean completely, as in 100%.
I literally had to attach it to another Mac and restore it to the original factory settings just to get it activated so I could have a phone! Everything was reset. I have to manually redo every single setting, re-add all my email accounts, my wireless network settings, EVERYTHING. Trying to restore from a previous backup FAILED.
Luckily my Contacts are backed up on MobileMe so I didn’t lose them, but it’s still a nightmare.
