okay so im planning on buying a ps vita for several reasons however while hunting for a good deal i stumbled upon the "instant gaming" version that comes with 4 games, 1 year of playstation plus, and a 4gb memory card, however this version is a 3g/wifi version rather than the standard wifi version the 3g is only available to those who have at&t, i however have sprint. now i wouldnt want to skip on this bundle. so if i were to get this bundle would i absolutely have to use the 3g (paying monthly and signing up for at&t) or could i ignore the 3g part of it and just enjoy the gaming without more fees? PLEASE HELP ive been hunting for an answer online but could not find it.
