My friend got the new iPhone 4 and gave me her old 16GB 3G. Her only request was to delete her info so I don't have the passcode and can't check the current firmware or baseband version.

What's the best way to upgrade to 3.1.3, 4.01, or 4.1 while keeping the ability to unlock? I think I need to be using redsn0w but the info on the 3G, not 3Gs, hasn't left me feeling confident even though I've been jailbreaking since the beginning.
Thanks.
