Nav N Go / Gomite prototype demonstrated yesterday, a company called PosiMotion claims that it has the "world's first wireless GPS" accessory for the iPhone. To prove it, they've launched a two-page website. Fishing for some of that iFund dough are we boys? Anyway, according to the site the G-Fi WiFi GPS receiver will support the iPhone and iPod touch and is expected to ship this summer. Really though, how much confidence will VCs have in an upstart still running on the ol' Cingular network?
