How To Unlock iPhone 4S No Jailbreak (GSM Only)

This guide will show you how to unlock your iPhone 4S without jailbreaking it by exploiting Apple’s Activation procedure bug. Enjoy!

Step 1: Insert your carriers original SIM Card (Note: At this point only the AT&T Method is confirmed working)

Step 2: Dial 611 (Customer service hotline) then drop the call after a few seconds.

Step 3: Turn on airplane mode. While airplane mode is on, take out your SIM Card.

Step 4: Insert your T-mobile SIM card and make sure that you are still in airplane mode.

Step 5: Once your T-mobile SIM card is in, turn off airplane mode. The apple logo will then appear on your phone.

Step 6: The edge network will automatically turn on. Once you see the E in the top corner, wait about 30 seconds and turn your phone off.

Step 7: Turn your iPhone back on. You will see the activation screen. Once you see your cellular data bar appear in the top corner, select “Use cellular connection”

Step 8: Eject your SIM card. You should see the activation screen again. Once you do, pop your SIM back in and you should be unlocked!
