I did the search, problem is I am an old fart and need people to be explicit yet simple. I had a wifi ipad and was told I needed a a 3g to use wifi. Sold the wifi and bought a 3g. Now I am running into problems. Do I HAVE to have a data connection or even a 3g connection. I was actually told the 3g ipads had a gps chip so you did not have to have either. bought the MotionX HD and it says there is no connection so no worky. I would appreciate someone explaining what I have and or really need. Thanks from the Baby Boomer Golden Years!
