Iphone Unlock

[sonyawhite]

Ok so i'm trying to unlock an iphone 4 i just got it has 5.0.1 and 04.11.08 BB. Now I tried using SAM but I have no clue what to what carrier the phone is locked so the SAM method is out of the question. So how do I sim unlock it using redsn0w ? I tried ultrasn0w but the BB is not compatible btw the phone is already jailbroken.

The only option you're gonna have w/ the 4.11.08 BB is purchasing an IEMI unlock online.

SAM unlocks only work if you have SAM tickets saved during the period that the backdoor unlock was exposed. Like Justin said, the only way for you to unlock an iPhone on that baseband is through an IMEI unlock which can be purchased on ApplenBerry (certified and trusted distributor) or eBay (I haven't had problems but use at your own risk, make sure you do your research and homework before purchasing)
