AppleNBerry now offering permanent IMEI unlock for AT&T locked iPhones
Often times, we refer our readers to AppleNBerry, the official reseller of the Gevey hardware unlock for certain iPhone4/4S firmware and baseband combinations. Unfortunately, the Gevey unlock is not compatible with all basebands so some users are still stuck with a locked device. Earlier this week, AppleNBerry began offering a new IMEI unlocking service which will permanently, and officially unlock your device without needing to jailbreak. Unfortunately, this is not an inexpensive solution. An IMEI unlock is going to set you back $150, but if you have an AT&T locked phone, with a baseband which is not unlockable, it may be your only option to unlock.
Before purchasing this unlock, we must remind you that recently AT&T began unlocking devices themselves for free as long as the device is off contract, not blacklisted and you are the original owner. We would suggest you try to get AT&T to unlock the phone before resorting to AppleNBerry's unlock. Once you submit your IMEI and Serial number, AppleNBerry will e-mail you after the unlock has processed(1-2 business days according to their website). After that, all you need to do is sync with iTunes and your phone will be permanently unlocked.
