Recently Tom Tom announced a GPS iphone app for 100$.. quiet expensive I think.. not gonna pay more than 20$ for any iPhone app;) would a service model work for iphone apps?? Or is it already there that I am not aware of? say pay per direction... or even better how about an ad supported GPS service on the lines of flixster?? Turn right now.. But I suggest you go straight and get some nice coffee down at Petes..
