    I am trying to find an iphone 4 to use overseas in asia with their sim card.

    I have a few questions. I have a 4S so everything i know about unlocking and jailbreaking does not appy to iphone 4

    1. what firmware and baseband do you have to be on to be able to unlock a US iphone to use over seas in asia

    2. any carrier phone will work yes? Ex: if i get a verizon or at&t wont matter correct?
