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!!!
