what a moron - "VZ and ATT don't want 4G b/c saps battery life" . . . that is well researched knowledgeable commentary at its best. The crap they peddle to the masses should be outlawed, really and I am pretty liberal.
in short, they have no idea what they are talking about when it comes to this technical stuff . . . 4G standard is not in true existence yet it is still more of a marketing tool right now . . . why do you think ATT wants T Mobile so bad? Sprint after building out Wimax is going to LTE and VZ network is far from complete . . .
there is still time for 4 g phones . . . that said it makes sense if there is a iPhone 5 and it is a world phone and sprint does have the 3 month exclusive - that it would be a 4g capable of running on wimax and lte - since many countries (including greece I believe lol) run Wimax . . .
