OK. I found this 2 days ago, and I'm afraid I'm just getting around to sharing... sorry.
I'm not sure if you have ever used Google Maps. Well, if you haven't it is great!
They have added another wonderful piece to their already wonderful puzzle.
It is Google Maps for Wireless Palm devices. It was specifically made for the Palm Treo, but it also works on my Palm TX. Only difference is I'd have to be at a hot spot to use it.
Anyway, it works on a boat load of devices.
Anyway, very cool!
Check it out.
