So today kinda sucked!! I was sending some pic and video to a friend and whoop my phone re sprung itself!!! and when it woke up all my texts were gone!!! I tried a reset, this didn't help! So after alot of yelling I did a restore to about 10 days ago.. Got everything back but now when I plug it in my phone says iTunes could not check for an update to your carrier setting. Unknown Error occurred. (1631) So i go hunting through my settings .. in General>About >Carrier it says AT&T (null) So I am running 4.2.3 on a redsnow jb .. I thought it was the carrier logo I changed.. so I took it off.. didn't fix? should i restore and redo the jb? i really hope not? other ideas anyone???? thanks in advance!!!
