Applenberry.com's AT&T GSM iPhone IMEI unlock service only unlocks U.S. AT&T iPhone models, which includes iPhone 3G, 3GS, 4, 4S, and the new iPhone 5 regardless of firmware and baseband. The only information required for this purchase is the IMEI number of the iPhone.
To purchase this service, you will need to locate your iPhone IMEI number on your iPhone by navigating to Settings → General → About and scrolling down until you see your 15 digit IMEI.
After purchase, your IMEI is processed by our team and sent to our unlock servers. The unlock process takes 1-2 business days. You will receive an e-mail confirming that your iPhone has been successfully unlocked with instructions on how to confirm your iPhone unlock status. Once your iPhone has been permanently unlocked, you can reboot, restore, upgrade, and jailbreak your iPhone.
In extremely rare cases, your iPhone IMEI unlock will be delayed, or we may not be able to unlock your AT&T iPhone. Please contact our Technical Department by submitting a support ticket.
