About the gps and navigation... know Verizon used to lock down gps on their smartphones and you had to subscribe to vz navigator and pay an additional $10 per month for it. And you couldn't use gps with other apps. That was back in '07, they may have unlocked the gps on their smartphones now, I don't know. That's one of the main reasons I switched to Sprint.

As for Sprint navigation and Google maps, I use both. Both are very good. I mostly use Google maps its pretty awesome since the last update. Give it a try. It seems faster and more responsive when scrolling around the map during navigation. Plus Google maps integrates with the EVO's voice search feature. Sprint navigation does too somewhat... I think.
They're all nice navigation apps. You can't go wrong with either one.
