Hi all, I'm torn between a Wifi or 3G model and had a question. I wouldn't really use the 3G in the iPad because I can just MyWi it from the 3GS. So the only 'real' reason I'd get a 3G is for the GPS receiver. My question is if there is an app that exists (JB or regular) that will allow my iPad to use by iPhone's GPS? The maps and everything on the iPad would be incredibly greater than doing it on the iPhone.
