If I walk into O2, buy a Pay&Go iPhone 3G, will I be able to unlock it to any sim on its supplied base band with firmware 2.2.1? I have looked on the dev team site, and it is a bit confusing. A simple yes no answer will be fine, or if you have a little more time, tell me if its yell0wsnow, or pwnage I need to use to unlock it. I used to keep up with iPhone unlocking, but lost track of it a while ago! Thank you for your time.
