If you have a factory unlocked iPhone, you can upgrade without any problems. If it is not locked at the factory and then the update will lock the phone. There is a way of 3.1.2 unlock software using software blackra1n, which requires jailbreaking. Do a Google search for Blackra1n (yes, the spelling is correct) and you will find instructions. You may want to hurry, because version 3.2 of the OS may be today.
