Hey...I just got a 1.1.2 iPhone for christmas. I downgraded to 1.1.1 jailbroke and then upgraded to 1.1.2 and got everything working fine. The problem is...I can still receive and place calls but I cant send or receive texts. I was for a while afterwards but it stopped after about 4 or 5 hours. Any chances that this is because of the jailbreaking? its a legit at&t sim with a legit at&t contract activated through itunes....i was thinking maybe it could be because i ported my number from verizon? any help???
