Hi, i have been searching forums for a couple of days now and i am still none the wiser. I live in the UK and i am looking to buy an iPhone and i am in a contract with Vodafone so i cant change. I have two questions; 1. Which phone would be a better choice to buy, the American version or UK, as i can easily get either. Which would you choose in my situation? 2. What is the difference between, jailbreaking, unlocking etc. If anyone has advice on which phone to get i would be really greatful. Thanks for your help.
