https://www.apple.com/iphone/LTE/ Is it better to purchase the iPhone in the US or in the UK for best compatability for networks? I'm in the UK until Nov. 14th, returning to the US until January, and then I may be living here for a year then. I want a phone that can work best in both countries, but I'm not sure if the 1st set of phones will be best (A1549 / A1522) or the 2nd (A1586 / A1524). It seems that the main difference is the 2nd set offers support in the TD LTE Bands - but does that mean that it can support the other networks (ATT/Verizon) as well, or no? I'm confused by what is meant by the carriers listed beside the versions when a lot of the same bands are covered.
