So I'm planning on purchasing the new Iphone 5 from AT&T (since it's GSM) and later taking the phone to Germany. (I'm in the military and being stationed there for 3 years) I know that AT&T will unlock my phone when I cancel my contract (AT&T honors military orders for overseas deployment) but my question is this... QUESTION: According to this http://www.apple.com/iphone/LTE/ I would have to purchase the A1428 GSM model but will I be able to use it in Germany? Apple will be selling A1429 GSM Model with different LTE Band support. Does this mean that if I take my unlocked AT&T A1428 I wouldn't be able to get LTE service in Europe? Thanks for all the help in advance!
