I'm from england but i live in the USA. I'm might only be here for another year so concerned about being tied into a 2 year contract. What happens if you need to break the contract - do you have to pay a big fee? Also, when I go back to england for holidays I want to be able to use my UK simcard in my phone. Do the network providers in the US allow this? I guess I could purchase an unlocked out of contract phone but with Apple Care plus and tax the 64GB I want comes in at $1000. Seems an awful lot to spend on a phone!
