My wife and I were looking into getting the sprint 3G/4G over drive pro. We are in washington & we have service in our area for this. Where 4g is not available it switches over to 3G capped at 5GB a month. The 4G is unlimited though when you have it. At 49.99 a month it seems reasonable to me, connecting up to 8 devices? I would just like to know if anyone has tried this with their iPads and how's the experience?
