Enable GPS on treo 800w use 3rd party application

[vansky]

understand, this device should be used under Sprint (while in US), but since i bought it in Indonesia, I cant use the GPS since it would be brought by Sprint Vision to enable it. My question, is it possible to use 3rd party application (instead of maps & sprint navigation) to run the GPS on this treo? what you would recommend (and is it applicable) and how to set it?

Thank you for the suggestion and sorry if this been already questioned before (if so and possible, pls direct me to thread's link)..

warmest regards..
