    Hi I have an iPhone 4 16 gb for at&t
    I really want to use it for tmobile
    Many told me it's impossible to jailbreak and unlock it
    But I jailbroke it and have Cydia installed on it.
    (i think it's tethered ? every time i reboot it i have to plug it into computer and go into DFU mode with redsn0w in order to use Cydia)
    Anyway I'm trying to unlock it and I've tried almost everything.
    I have tried downgrading bb and iOS but it's not working
    I don't have any SHSH blobs and I don't know how to get them.
    Someone please help me!!!

    Other people saved their baseband from previous firmware releases.
    Currently there is no unlock available for your baseband version. The baseband cannot be downgraded.
    Not every iPhone can be unlocked.
