Hi, I have just moved to Africa from the states and I have my ATT 3gs Iphone with me. Currently it has the 3.1.3 firmware and 5.12.01 baseband. I would like to unlock it so that I can use it on the Orange network here in northern Uganda. I would like the 4.0 software but would be happy with anything. I have been trolling through the forums but can't seem to find the right combination to match my situation. I do still have my att sim card. Any thoughts? I am sure this has ben discussed a million times already so thanks for any advice.
