I was wondering this last night when I was reading thru the data plans. We're on ATT right now with unlimited data plans. I vaguely remember seeing a plan that allowed me to select 4gb with Mobile Hotspot. Is this something that ATT has designed to get people OUT of the unlimited data that were grandfathered in? I'm considering this as an option as I have never nor my other 2 iPhones on the family plan ever get near the 2GB mark, this could be a way to save money plus getting rid of the unlimited text messaging and going with the lowest along with iMessage I should be able to save even more. Ideas?
