How to Unlock iPhone 4s, 4 & 3GS without Jailbreak????

Well, here's a new trick has been discovered by developer called Michael Capozzi, this trick allows users to unlock iPhone 4S, iPhone 4, iPhone 3GS without jailbreak and without Gevey SIM.
He has been kind enough to also give the following step-by-step guide to unlock iPhone 4S using the bug in iOS 5 to work on T-Mobile USA:
Note: You will need to cut the T-Mobile SIM to micro-SIM size for it to fit iPhone 4S's SIM tray.
Note: Only AT&T iPhones can be unlocked with this trick.

Step 1: Insert original carrier AT&T SIM card

Step 2: Dial 611 for AT&T customer service hotline and drop the call
Step 3: Turn on Airplane Mode
Step 4: Take out AT&T SIM card
Step 5: Insert T-Mobile SIM card
Step 6: Make sure WiFi is off ( also tap on ‘Forget this Network” to make sure it doesn’t connect automatically later)
Step 7: Switch off Airplane Mode and iPhone will search for network. This is followed by the Apple splash screen appearing.

Step 8: Activation Required will be displayed on the screen
Step 9: EDGE network will activate automatically – notice the ‘E’ on the top left corner of the screen
Step 10: Wait for about 20-30 seconds and turn off the phone
Step 11: Turn on iPhone and the same Activation Required screen will be displayed
Step 12: When you see one signal bar, tap on Use Cellular Connection
Step 13: Eject SIM card
Step 14: Activation Required screen will be displayed the second time
