Is this true? Can the WiFi-only iPads actually pull GPS data from the iPhones when tethered?
Ive seen this claim made in a number of places, but have yet to try it for myself... and I'm very skeptical about it. I may have to just try it and see... but - the fact still remains - if one wants GPS capabilities on a Wifi iPad, one must have some sort of external source for the GPS data, and that can be done with devices that connect to the iPad directly or via bluetooth.
Edited to add:
I tried this... connected my iPad3 to my iPhone4S via personal hot spot... and the stock Maps app did indeed get a location fix via the iPhone... then I went for a little drive. There's where it went to an end user experience that I'd rate something less than desirable... lag between where I was & where the map showed I was, and while moving, the location was not as accurate as when I've used my iPad with the BadElf GPS receiver plugged in - the iPad/BadElf combo is every bit as good as my Garmin Nuvi765t.
