I had an iPad 2 on Verizon for a little over a year. Apple replaced it with an iPad 3 about 3 months ago. Each month I am using about 30% more data than I used to use on the iPad 2. I am not using it any differently. I don't watch videos I just email and check out websites. I am using the iPad 3 exactly the same way I used the iPad 2. My thought is that the 4g uses more data than 3G. It doesn't make sense to me. I would think it should use the same amount of data. I am wondering if it is the iPad itself causing the problem. Has anyone else noticed this problem.
