Here's the background: I moved to the UK from the US, but because I had a locked ATT 3GS Iphone (2 months from contract end) I couldn't use my phone with a UK carrier. So, I jailbroke the phone with Redsnow on IOS 4.3.4 (if I'm remembering correctly) this was about 9 months ago. No location services, but I had a phone. Next, I read last week that ATT was unlocking out of contract phones--I call, submit the unlock request, it is approved, and I restore the phone to IOS 6 thinking it will clear the phone of the hack and connect with iTunes to get the ATT unlock. Now, I have an Iphone stuck at the activation screen that does not acknowledge the presence of any SIM card I put in it. At first I thought the ATT unlock hadn't gone through, but now I realize I restored a jailbroken phone improperly. What do I do to get back to my original store bought Iphone settings and get the ATT unlock? Help!
