iPad WiFi model gets GPS when tethered to an iPhone
Apple has finally brought wireless tethering functionality with iOS 4.3. It is called Personal Hotspot and allows users to share iPhone’s cellular data connection with other devices over WiFi connection.
For instance, you can connect your iPad WiFi only model to the internet via iPhone. There's one less reason to pay additional $130 for a 3G iPad. There is another difference between iPad WiFi and iPad 3G - GPS. Well, it looks loke WiFi-only iPad inherits GPS positioning capabilities when you tether the tablet to an iPhone via the Personal Hotspot feature.
Kyle Carmitchel from TabletMonsters discovered this by accident and posted a video to prove it.
This is really cool, but many iPhone users would still buy iPad 3G, because iPad 3G is a complete solution and you don't have to setup Personal Hotspot any time you need internet and GPS.
