I have an Ipad 2 and a Mifi unit. I had the Ipad 1 with 3G but sold it. I had the Motion GPS on the 3G one and I just tried to put it on my Ipad 2 but no go. Are there any of the Navigation apps that do not require 3G but will work with mifi? I have looked but I did not see any that tell you. I do not want to pay $50 for something that will not work.
