Hi i would sugest you stick with what you have ,the gps satellite signals are allways above and thru the horizon and using a phone or hand held dedicated has the same issues in built up or wooded areas im afraid. i currently run with a garmin etrex and a nokia n96 both of which work very well indeed ,once you have the nack and know, feel how stuff is hidden then it counts almost as well as the gps unit its self , ive been out without any gps just with the aid of a note pad and a good read of the description then a look on google earth prior to departure before.
I only have one or two issues with the phone and its the battery problem gprs cains it! oh and screen timeout but no real biggy.
Finally it does pay to keep good notes and try not skimp on detail like THIS IS A CITO CACHE etc etc when you are saving paper by not reaming out printoffs
very best regards and a happy new year
Shawn
