Ok GoPhone now has a $50(putting it in comp with say MetroPCS) unlimited plan, with No contract, unlimited text, talk and Data!! The drawbacks are you have to purchase the device with no discounts, and the line of devices kinda suck. and AT&T is ONLY a 3G company, since they have no 4G operations in reality yet!!
