I've not been Geocaching yet (been meaning to for years) but I have been training for a 50km walk, so have been walking a lot and using the iPhone to record my trail. Obviously results may vary, but: I've used GPSKit, a ~$12 app i think, to record my path. It makes a gpx file, i can have groups of waypoints and it can narrow them, it can work without a data connection, but needs data if you want a realtime satelite map of where you are, eg it can't save it's own map. It works well, it has NO CACHE functions though. So i'll deffinately be grabbing this app when it comes out I found if i drop the screen brightness, the iphone can record walkies for approx ~ 4 hours. However I've made an external belt back NIMH pack with regulator that keeps the charge topped up. Using this i can get over 10 hours before the pack goes flat, and then i have 4 hours of iphone use left, enough for me easy. It's great to go for a walk, get home, and see in google earth exactly where you've gone. (never had a GPS till now) I found that it locks on very quickly, and had no trouble keeping good accuracy even with the phone buried in my backpack.
