Never heard of that one. What OS do you have installed? Did you recently upgrade to a beta OS?

Wirelessly posted (All the cool kids are doing it)

Sounds like the unlock didn't take or that it wasn't a true unlock...did you just recently get it unlocked and its causing this issue?

[BlackDiamond]

No the unlock is fine it was fine until like a week ago and then bam! As for the O.s it is 4.2....but like i said it dosent hold a signle after the first 30 sec of start up...

WHAT TO DO

where did u get the phone from, i might suggest talking to whoever did the unlock.

[BlackDiamond]

I got it off of here.....i cant remember who but it was a MOD jsanders i think IDK...ill look into that though

For resolution of the PUK code issue, you need to contact your carrier's customer service. Entering the wrong code to the PUK unlock message too many times will fry your SIM card, requiring you to replace it.

No i bought it from "lunkhead" i will see what i can do

[gbnemail07]

yeah i would just ask who you got it from, they might know whats up, plus if it was from a MOD they might know whats wrong, did u try your SIM card in a different phone just to confirm that it is working properly?

[BlackDiamond]

Yeah i called AT&T and they are sending me a new sim card.....how do i save all my contacts so i dont lose all those....
