Although there’s mixed response to the method to unlock iPhone 4S, 4 or 3GS for free, here’s the way to unlock your AT&T iPhone 4S anyway. There’s no harm in trying – so you can try and tell us if it worked for you.
Only AT&T iPhone 4S can be unlocked using this method and for the moment, only T-Mobile SIM has been tested. Gizmodo prompted us about the method via Pastebin.
Here’s how to unlock iPhone 4S, 4 or 3GS for free – no need to hack or jailbreak.
Insert the original AT&T Carrier SIM.
Dial 611 for AT&T customer service hotline. After you dial it, drop the call.
Switch on the Airplane mode on your iPhone 4S.
Make sure the Wi-Fi is switched off before you proceed.
Remove the AT&T SIM and replace it with the T-Mobile SIM.
Tap on ‘Forget this Network’ so it does not connect automatically.
Now switch off the Airplane Mode and the iPhone 4S will start searching for available networks.
“Activation Required” screen will appear.
The EDGE Network will get activated automatically – (you can confirm this with the ‘E’ on the top left corner of the screen.
About 30 seconds later, switch off your iPhone 4S.
After this, switch it on again. The “Activation Required” screen will pop-up once again.
When there’s ONE SIGNAL bar, tap on Use Cellular Connection.
Remove the SIM card. “Activation Required” will come up again.
Instert T-Mobile SIM again and that’s it! Unlocked.
Although the method is out for some hours now, we have seen mixed response to this. While some people have reported complete success with the method, some people have reported that nothing happens after trying out this a number of times. Also, this works only on the AT&T carrier – and the test has been done only with T-Mobile (the only other popular GSM network, Sprint and Verizon are CDMA).
Since there’s no hack or jailbreak involved, it’s comparatively safe to try this unlock iPhone 4S for free method any number of times. You can also restore the iPhone 4S should anything go wrong. And yes, we are not to be held responsible should anything go wrong.
Having said that, it’s quite obvious nothing can go wrong actually – it’s just a try. No harm in trying!
