"Unlock AT&T iPhone 4S Baseband 1.0.11, iPhone 4 Baseband 4.11.08 and 3GS Baseband 5.16.05"
Some of the comments say it worked but what I want to know is if it's permanent or how long it lasts (ex: if you turn off the phone does it reset). I don't have an alternate SIM card to use so I'm hoping someone has tried this already.
