Distribute Go Maps
How do I distribute GoMaps to my users iPads?
One of the great things about GoZync is that it lets you get new versions of your mobile app to your users without requiring them to use iTunes.
You'll get the file to them a bit differently the first time, and then after that they'll get it by clicking a "check for new version" button right within your app. You can see one of these on the Home screen for GoMaps.
This is all built into GoZync and described in the GoZync docs here: Distributing Mobile Files.
