I went out today and found my first cache!! I was very excited, and I am very hooked. Too bad my lunch hour isn't longer.
I was having trouble with the whole SD card downloads, not sure what the issue is there, but I'll figure it out.
I ended up buying/using 'cachemate' as suggested earlier, and really liked that. I also added an app called 'GPS Essentials' that was free and very useful.
