Hi guys, I cant believe what just happened. I was trying to update my non jailbroken iphone to 3.1.3 software. All of the sudden it says ' unexpected error, cannot update iphone' . and now , everything is gone on the iphone and i have to restore! I hope i can restore from backup and it will use the most frequent backup , but else, im screwed... Anyone have this problem when trying to update to 3.1.3?
