Well, these aren't free (they're actually a bit expensive), but I thought I'd repost in case someone was interested.
Geocaching App! It is for the iPhone, but can be used on your iPad. Why would I use it on my iPad? Paperless caching since my gps can't! However this is a disappointingly expensive app. A great app, but is currently $10! It allows for me to carry offline infor about all the caches I have saved for hunting. You will need to decide if this high price is worth it or not. This links to geocaching.com and their info on the app with tutorials and a video.
