Once you have created and modified data in CartoMobile, you will want to get it back to your computer. This process involves copying the data files back from your device to the computer using iTunes, and is basically the reverse of the process of getting data in to CartoMobile, and since the data is always kept up to date, you can do this at any time.
Copying a Shape File from your Device
Attach the device to your Mac or PC and open iTunes
The device should show up in the source list in iTunes
Select the device in the Source list and choose the Apps tab
The Apps tab should be selected
Click on the device button at the top of the iTunes window
