Be forewarned

This works, but you will have to pay money to mail your data the first time. To be precise, you can email 5 minutes of data free each time, but must pay if you are sending more. You can use this to geotag an afternoon of photos in the same place, or else start and stop the app every few minutes if you are moving. I will use another app that is really free.
