I had my first Ipad for three years, 64 gig, wifi.. G3. I had AT&T service and never went over my two gigs. I don't stream movie, but will look a clips that people post to Facebook. I just bought the latest version Ipad from Sprint. Not knowing the Ipad Air was coming in two weeks. My Sprint data plan is $15.00 for two gigs. This was one reason I went with Sprint. 2 gigs with AT&T was $25.00. In three years i had never gone over my 2 gigs. I don't stream movies. I have poor WiFi in my very large home so often have 3G on. In only ten days i had used my new 2 gigs with Sprint. I called to increase to three gigs, guess what? No 3 gig program.. 4 gig for $39.95 and 6 gig for $49.95. Needless to say i am hacked! sprint the company that offers free unlimited data for life on my phone, wants another $40-50 bucks a month to my already $200 monthly plan. I have find how to get something that will extend my wifi back to my office from the far away kitchen. It seems Sprint is calculating my usage in a different way. Perhaps as the 3 G is searching.. It is using mgs all that time. It seems it searches alot. But my question today is.. This ipad is very hot to the touch in the back. I have it in a Zagg keyboard case, but had it in another case last week and it was still very hot. Why? Do I need to return it?
