First of all, sorry if this seems a bit repetitive. I have been reading the forums thoroughly but would like some specific advice. I am in the US for 9 months of the year and back in the UK for 3 months. I have a vodafone contract with my current iphone in the UK which I use here on an AT&T pay and go sim. Basically I am looking at which are the best options for me to buy an iphone 5. I visited apple today and they were more than happy to sell me a full price iP5 but only had 16gb. I am not overly concerned about LTE at the moment as it doesn't look like I can get it here in US with my current circumstances. My questions are; 1. Which iP5 model will support 3G on Vodafone UK network? ( I know, no LTE) 2. If either, which carrier would you recommend? (can of worms I know) 3. Is it best to buy the phone full price to allow change of sims between US and UK? 4. Is there a plan that would be ideal and get LTE service in the US? Many thanks in advance.
