    Restore as new.

    Try a new/different SIM.

     

    Are you still using AT&T?  If not, who are you using?  Are they a supported carrier?

    Hello diesel

     

    Am not using AT&T , using it in india. The phone was locked when i bought it to india and i have contacted AT&T to have unlocked which in turn upgraded the software to 5.1.1 9B206. This problem started a week ago and then i upgraded the software to 5.1.1 9B208.

     

    It will try to use a new simcard today and update you. If  the sim replacement resolves it , i would say : YOU ROCK . Would keep posting.

     

    Thanks
