I have found myself this past month needing to use my WiFi iPad 3 where no WiFi has been available. I will soon be in that situation again. I want to solve this immediately, so I am looking to do one of two things: 1: Sell the iPad and get a 3G iPad mini. I don't have the money for a gen 4 Cellular iPad, but can switch to a mini for the same price. I'm less apt to do this because I like the size and retina display of the 3. My iPhone 5 and MacBook are also retina. 2: Change my AT&T data plan from grandfathered unlimited to 4GB shared. My wife and I use less than 2GB a month, but I would never be able to get this back. Bill would be $10 less a month. What do you think I should do?
