I have an unlimited ATT data plan from the iPad 1 that I have been using I live in SF but travel around the west coast periodically. I am wondering whether I should go ATT even though the network is less comprehensive - and maybe slower? - or switch to Verizon. My only reason I think to stay with ATT is to keep the unlimited package, but I am nervous that a month or two from now they might cap it like they did my unlimited iPhone data plan. I tried both the ATT and Verizon iPad's at the Apple store in the Marina area of SF, and neither had LTE showing up. Having hotspot capability is nice too, though at data rates not sure how much I would use that. Suggestions?
