A strange bug on iOS 5 has apparently been found by Michael Capozzi (via
Chronic) that allows the carrier unlock of the AT&T version of the iPhone 4S
, iPhone 4 and iPhone 3GS without any software or hardware tweaking.
The unlock reportedly allows you to use your iPhone on the T-Mobile's
network with Edge data speeds in the U.S. as long as you have a T-Mobile SIM
card.
To get started, you will need to cut the T-Mobile SIM card so that it fits
into the Micro-SIM card slot in the iPhone 4S.
Many people claimed they have exploited this bug and have successfully
unlock their AT&T iPhone 4S for use with the T-Mobile carrier while others
said that it's not working for them, Gizmodo reported.
Although the method appears to work, it has not been tested by the tech
experts at the IBTimes. If you want to unlock your device on the iOS 5
firmware by exploiting the bug, follow the directions below:
Must Read
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

6. Make sure WiFi is off (also tap on 'Forget this Network" to make sure it

followed by the Apple splash screen appearing.
