Working IOS 5 unlock for IPhone 3Gs

Is it possible to unlock IOS 5 for 3GS so it will work on the three network?
Answer #1
Nope, there is no unlock for iOS 5 (BB 05.16.05)

Only thing is that if you have some other version off BB what can be unlocked, make CUSTOM IPSW for iOS5 and preserve BB from updating, then you will be able to use ultrasn0w as unlock!
