So I am on the fence about whether to go for at&t's iphone plan with only 4gb of data for 2 iphones, or 60 dollars for unlimited for 2 users on verizons plan. The real question is, when I JB my Iphone how much data should I expect to use. How many Gbs do you usually use a month? I'd prob get about 3 gb at least outta at&t's but idk guys help me make up my mind here... is 4gb a month enough!?
