    I've done some searches and found some very old posts about using an iPhone 4 on O2, but can't find anything recent. I'm going on a trip to the UK and would like to be able to use my iPhone 4, mainly for calls, texts, and surfing, but also occasionally for GPS if possible. I have an O2 sim card- is there a way for me to unlock the phone to use the card?

    I'm currently running OS 6.1.3 and Firmware 04.12.05

    Any help or suggestions would be greatly appreciated!

    No need ask AT&T to unlock or an IMEI unlock online, there is a big thread on here use search.
