AT&T Prepaid Sim Card with iPhone 3GS?
So I stupidly tried to jailbreak 4.3.1, which I didn't know it wasn't the best idea. After getting my phone stuck in some kinda mode, I restored it, but iTunes forced me to restore and upgrade to 4.3.1. So my phone is basically useless at the moment, but I really need it in case of emergency. My phone is not unlocked or jailbroken. I didnt shsh my phone either so I cant downgrade. Is it possible to buy a prepaid sim card from AT&T and use it in my phone? Sorry if this has been asked a lot. I'm still learning.
