If you're using Phapper, you should really move on over to Mologogo (MObile LOcation). Not only did I finally address the North America only issue (which means this one has satellite maps), I'm working with a brilliant partner who's taken care of all the server-side issues and provided a ton of great ideas. You can now view friend's locations, follow a friend, annotate locations, etc. etc. Phapper is officially unsupported -- Mologogo is now the way to gogo.

Did I say "free"? Yup. Go sign up now!
