Hello all I am totally new to the iPad as I am coming from the Android platform, so please excuse my ignorance. I was at first looking to get the WiFi only version of the iPad because I have a Nexus One running on AT&T and I would be able to connect the iPad to my normal WiFi at home, and when I am out and about in the car I can connect to my Nexus One using the Nexus's built in WiFi hotspot feature. However, I discovered in research that the WiFi only version does not have true GPS which would preclude using the iPad with navigation apps from the App Store. So here is what I want to do: buy the 3G iPad WITHOUT purchasing a data plan for the iPad and just connect it to my Nexus One via it's wiFi hotspot feature when I am in the car. I just need to know if I can use GPS for navigation apps on the iPad WITHOUT 3G data? I know this is probably a stupid question but I just want to make sure the GPS can be used when a SIM card is not installed in the iPad as I will not be purchasing a data plan. If this will work I will be buying the WiFi + 3G iPad for $629. Obviously I would be buying the WiFi only version if only it had built in GPS...so I'm hoping my I can get what I'm looking for by spending the extra $130. Thank you for any help!!
