Dear Goldriver97,
I'm a developer at the InfiniDroid team.
If I may answer your questions:
1) There will be no cost from our side, the App will be available for free.
The storage backend is of your choice and the price is according to your price plan. So if you use for example the free dropbox account you will have 2GB of storage for free.
2) InfiniDroid is not simply an App, its an extension of the Android OS, that provides intelligent and transparent
storage management the way it should be.
Since we are currently working on a real device demo video, may I ask you for an App that you would like to see demoed with InfiniDroid?
Hope this clears up your questions?
