so i saw this article (Vlingo Update Brings InCar Mode Exclusively for Sprint | Android Phone Fans) and it sounded pretty interesting, especially with a sprint connection. i remembered seeing this a few days ago when the sprint zone notification showed up in my status bar. well, i pulled up sprint zone and lo-and-behold, there's vlingo. i selected it and was directed to the market, but then received "The requested item could not be found." what gives? i was able to search for it directly from the market. anyone tried vlingo? how does it compared to similar google apps?
