iPhone 4S is now available in more than 30 countries worldwide and Apple is eying to launch the phone in 70 countries by the end of this year. In some countries its available as carrier branded phone with their special contract while in others its available factory unlocked so that users can use their choice of the carrier for their iPhone 4S.
Unlocking a carrier locked phone is not a cakewalk, sometimes it requires some modifications be it hardware related or software part, no matter what way you see it you need to jailbreak the phone,but how about an unlock method which allows you to unlock your carrier locked phone without any hardware or software modifications being made on your iPhone 4S?
Michael Capozzi apparently has found out a trick to unlock the AT&T branded iPhone 4S, here’s how it goes,
Step 1: First of all insert your AT&T SIM into your iPhone 4S, if the SIM is not already into the Slot.
Step 2: Make a drop-call to 611, after dropping the call, activate the Airplane mode.
Step 3: Now Remove your AT&T SIM and replace with the T-Mobile SIM.
Step 4: Make sure that the Wi-Fi on your phone is deactivated completely by disallowing any automatically connected networks.
Step 5: Deactivate Airplane mode. The device will begin searching for a signal. You will see the usual Apple splash screen and the activation screen.
Step 6: EDGE network would automatically get activated.
Step 7: Wait for 30 seconds and then switch the phone off and switch it on again, You will now see the Activation Required screen.
Step 8: Once you see the signal bar on the phone,hit Use Cellular Connection.
Step 9: Now remove your SIM Card , then you will see the final activation notice.
Step 10: Re-insert your SIM Card and thats pretty much it,your phone is now Unlocked.
