It's ok now since I got my phone replaced but dunno if this has happened to anyone else I jailbroke my 4S w/ the absinthe app on my computer, was enjoying my jailbreak and everything was fine except for a few random lock ups / reboots. Eventually I wanted to get my phone back to stock (since I could always jailbreak again at a later time as long as I don't update to 5.1), so I did a DFU restore through itunes and get the following error after it is restored and I go through the setup process: "Only compatible SIM cards from a supported carrier may be used to activate iPhone. Please insert the SIM card that came with your iPhone or visit a supported carriers store to receive a replacement SIM card" I went to the AT&T store and they give me a brand new sim card... no luck. It still gives the same error as above. So I tried doing a few more restores but had absolutely no luck and eventually just made an appointment w/ apple to get a replacement phone. Hopefully this is just me doing something wrong but has anyone else restored their phone since they jailbroke?
