Battery draining if using lte version in countries that don't support it? unlocking?
Im planning on buying the at&t version since im sure it will be cheaper than the international version (which is supossedly going to cost 780 $ -the 16 gb version- ) but i'm worried about the battery life, word on the street is that at&t is getting a lte version and im gonna use the device here in latinamerica , and we dont have lte, will the battery drain faster trying to look for a nonexistent lte network?
Also , i know is tought to tell since the device isnt out yet but do you think it'd be easy to unlock since its a samsung device, they're famous for being quite easy to unlock, or do tou think since ice cream it's a quite different version of android it'll be harder? what happened to nexus s? was it easy to unlock?
