Among the perceived downsides to purchasing a Wifi-only iPad 2 is the inability to use GPS. Interestingly, however, it appears that users are reporting that if you tether your iPad 2 to an iPhone, then it can utilize the iPhone’s GPS, thereby gaining its “lost” feature.
This was apparently discovered by Kyle Carmitchel on a recent road trip. He decided to open up Maps o his iPad 2 while tethered to his iPhone. Said he:
As we got closer, I decided to get some directions to make sure we were on track. I launched the iPads maps app, expecting to navigate the old fashioned way without GPS assistance — knowing full well that GPS only comes in the 3G iPad models. Imagine my surprise when my iPad pinpointed exactly where we were on the road.
Apparently this only works if you are using the Personal Hotspot feature (either officially or via jailbreak), and it is distinct from the usual Wifi triangulating features of the iPad. Long story short, if GPS is the reason you’re considering a 3G iPad, you might want to take a look at saving your $129 and gettinga Wifi-only model instead.
