He admitted he carried an ATT smartphone hookup box that enabled the connection and was piggybacked on his cellphone subscription.
He was fully wired with all that crap when he worked for Shell (they paid of course) and traveled all over the world. I just never bothered with it, never needed it. My world was electronincs design, not much consumer stuff. Designing the antennas used on the military PLGR handheld GPS is as close as I got to consumer stuff.
No problem. Good thing ignorance of something is easily curable. The WIFI version of the iPad doesn't have GPS built in, while the Cellular version does. That is one distinct advantage to buying the cellular iPad over the WIFI version. The iPhones all have GPS built in. . . and you CAN use the iPhone as a WIFI hot spot for the iPad or even a computer to connect to the Internet with. I do it regularly with my laptop. However, my iPad can also act as a WIFI hotspot. The only requirement is there is a cellular signal.
I prefer to use the WIFI signal from a cable source, though, because my cellular connection is only 10 GB per month before I have to pay extra. No movie watching on cellular. That eats bandwidth fast.
