    Hello Guys,

    I need big help with this lil problem I'm having with my Iphone. Some info:

    Iphone 3gs
    5.1 ioS
    baseband 05.16.05

    Ok. so I think it's unlocked. I recently changed my old phone to this one so i bought a sim card for it. And it either says searching indefinitely or no service. I cannot use my phone. Please any help would be great as I currently have no phone.

    Thank you

    Also forgot to add. I've tried a lot of things like taking the sim card in and out.
    resetting network data, re-installing ultrasnow and Sam. 3g on and off. Air plane mode on and off.

    Also when I go into setting. about. network. says not available. scroll down to carrier and it shows the carrier of the sim card (but still cant use it).
    or I go into settings. carrier, and its automatic on. if I go to turn it off it says unable to load network list.

    Your phone is not unlocked. The 3GS has to be on baseband 06.15.00 in order for ultrasn0w to unlock it.
