Hi and thanks for all your responses. The blackjack phone is a WM device, but it can't run GSAK. For some reason, I can only access Geocaching.com via a wap connection and it doesn't allow me to filter searches or do searches for unfound caches only. That is the reason I was wanting to use the gpx files. I will try using GPXsonar, if I can figure out how to load it on the phone. I ain't as smart as I once thought I was, but given time I will figure it out.
Thanks again,
Don
