If they are going to charge like $100 for this app on the App store...it will not be worth the price, unless it has a lot more features than what is in the version that is in the Sprint Instinct.

I don't know, sounds like telenav normally charges $10 a month, over two-years that is $240, over 4 years that is $480. I'd rather pay one flat rate, guessing tomtom would do this. Yes, your maps will get out of date, you could pay for updates, but I have had my garmin going on 4 years now and have not found the need to update my maps. Every once in a while you'll need to route into some new neighborhood and end up in a field on the GPS, but 99% of the time your good.
