    I'm heading to London next Friday and I don't want to pay the crazy AT&T rates while there. First, I don't want to unlock my phone. Can i use an O2 pay as you go sim card in my iPhone, or is the phone locked to only AT&T sim cards?

    Thanks

    Your phone is locked. The only way to use a SIM from another carrier is to jailbreak and unlock.

    Do you have to do both? I've been told that unlocking will suffice if you simply want to use a SIM from another carrier.

    How are you going to install the soft unlock without jailbreaking?
