[YouMayLose]

I use google maps and live search w my touch pro both work great.. even though my provider is metro pcs... I have seen GeoCaching for the TP on some sites although i dont do it I am sure it is done and can be done...never had an XV6800 so dont no how much better but I do know the TP is awesome if you enjoy windows based phones... as for stock rom I dont have the answer to that either as I didnt use the stock for very long but I dont remember it being bad at all...the GPS works pretty good..again concider I use Metro pcs as a provider so I use live search and google maps for gps and they do very very well....
I LOVE MY TOUCH PRO.. but I went from a basic phone for text/call only to the touch pro which does every thing except cook and clean my house lol
