Hey everyone! I just updated to 2.2 and jailbroke it when it was released, but about a week ago my texting just stopped working. I factory restored my phone and it still didn't work. Then I went to AT&T and asked for a SIM card replacement, now I can't even use internet on the edge network and I can't connect to 3G. I can receive texts but can't send. I can still make phone calls So the question is, is there any way to fix this? Otherwise I'm going to take it to the apple store, but pretty much anything they can do, I could do at home... other than hardware stuff. But if I do take it to the apple store and it had to do with something I did while my phone was jailbroken, will I still get a new phone? Also, I would of course restore my phone to legit mode, but would they be able to detect that my phone used to be jailbroken and would they void my warranty if the cause was a jailbroken app? Thanks!!!
