After much decision swapping I have decided to buy the UK iPhone from Carphone Warehouse this coming Friday. However, since I don't want another contract, and already knowing O2 WON'T accept me for one - I want to use O2 Pay as you go. I have read that by jailbreaking it allows use of any O2 Sim Card. Is this true? If so, could someone be so kind as to post a 1, 2, 3 step on how to do it, and where do I get the necessary files. Also, I only have access to a Windows machine - so everything must work on this. I will pay whoever manages to help me Thanks, JDT. PS: I've searched Google and the forums and found conflicting/confusing/completley unrelated answers.
