As another Newbie to this, can I add further questions. Currently I am using my Mobile Phone (Nokie E71) which works just fine, and I have "unlimited data" so doesn't cost me to use the geocaching software whilst out and about. 2 questions... when I go abroad, it would cost me a fortune to use - do I need to be "online" to use my phone as GPS??? Secondly, should I decide to get a GPS device, is there a good one that will also but useful whilst skiing (for speed, distance, altitude etc.)?
