iPhone 4S can reportedly be unlocked without any hardware or software changes
Michael Capozzi (via Chronic) has apparently discovered how to unlock the iPhone 4S (reportedly AT&T version only) without any software or hardware tweaking. The unlock will assist you in using your iPhone 4S on T-Mobile’s network as long as you have a T-Mobile SIM card. Before you get started, go ahead and cut down your T-Mobile SIM card to match your AT&T SIM card’s size. We’re working to confirm this works, but go ahead and give the following directions a try: 1.Insert original carrier AT&T SIM card 2.Dial 611 for AT&T customer service hotline and drop the call 3.Turn on Airplane Mode 4.Take out AT&T SIM card 5.Insert T-Mobile SIM card
Update: the unlock also works with the iPhone 3GS and iPhone 4, and will need to be done again if you reset your device. Continue after the break..
6. Make sure WiFi is off ( also tap on ‘Forget this Network” to make sure it doesn’t connect automatically later) 7. Switch off Airplane Mode and iPhone will search for network. This is followed by the Apple splash screen appearing. 8. Activation Required will be displayed on the screen 9. EDGE network will activate automatically – notice the ‘E’ on the top left corner of the screen 10. Wait for about 20-30 seconds and turn off the phone 11. Turn on iPhone and the same Activation Required screen will be displayed 12. When you see one signal bar, tap on Use Cellular Connection 13. Eject SIM card 14. Activation Required screen will be displayed the second time 15. Insert SIM card 16. Unlocked! If cutting down your SIM isn’t your thing you can obtain a microSIM through T-Mobile’s website.
