Geocaching App for iPhone

Hey guys,
The iphone app that I got was the one made by Groundspeak for $9.99 You have to get it at the app store or wherever you buy / get apps for your iphone.

Here's the link

I have used it alot and it works really well. The only thing of course is if you don't have good phone service, you don't have good gps service.

Hope this helps
