I ran into this when switching over from EVO 4G to 3D.
Scratch that. Just figured out that the free version will save App Data, but you need to be rooted, with SU privilege, and you need to specifically check the option to b/u app data. And before you do that you have to go into Options (in the app) and check "use root features"
Then you only have 30 days to restore unless you buy.
