I’ve been playing with this really cool GPS app for the iphone. If you are rockin’ a 3g or 3gs, you should be rockin’ this app. It will let you do most of what you’d want to do with a dedicated hand held gps (maps, tracks, waypoints, etc.), plus it lets you download those maps over wifi or the cell network, take and geotag photos, and share your location via FB, twitter, or email, send yourself kmz or gpx files of where you’ve been. In addition to google and bing maps, you can download maps from the totally open source OpenStreetMap, which I didn’t even know about (Zmurder, did you?). I seriously think that in a post iphone world, electronics that are not connected to the interwebs will seem increasingly dumb.

The light version is free and awesome, but I think the 2.99 upgrade is worth it, if for no other reason than to support what they are doing.
