    Hey :)
    First of all, i've been searching for an answer to this issue for like 1 year. I had my idevice unlocked (bought in UK and used in Portugal) and I upgraded it to iOS 5.1.1 but I couldnt activate it. My iPhone was frozen, I couldnt do anything with it. BUT, i moved 2 weeks ago to the UK and tried to activate it with the original carrier (O2) and didnt work. Well, I jailbroke it and it's activated now (using redsn0w). The iPhone is working like a iPodTouch. Oh, and don't ask me why but I unlocked it, I know I didn't need to, but, whatever.
    The issue is, i insert the original carrier sim card (O2) and it's recognized, but it's "searching" and getting "no service". :confused:

    Baseband: 06.15.00 (yes, it was built before the 32th week of 2011, i bought it in 2010 I think)
    iOS: 5.1.1 (jailbroken and unlocked)

    By the way, in general settings, it recognizes the SIM card and the carrier (O2 12.0).

    Basically, no signal or searching. What can I do ? :confused:

    Cheers mates
