Wigle Wifi Wardriving
Scan for wireless networks, map them on the device, and an "upload to wigle.net" button for easy submission to the database.
Wifi network scanning, mapping, and a menu option to upload to wigle.net make this a nice app.
Another wardriving app, includes mapping and cell-tower info. Exported files can be uploaded to wigle.net, but not from the app.
