I think I may one of the few that is interested in backing up app data from apps I purchase on the App Store, but is there any way to do this without jb'ing my iPhone? I sometimes need to delete apps off my iPhone and MBA to make space, but installing individual apps back always results in losing my data and I do not need to do a full restore to reinstall individual apps. I would easily pay $20 for an app that can do this without the need to jailbreak!
