Sorry but I'm nomally 4 years behind the times. I just came across this. It appears, if anybody is having the same problem, that App Backup and Restore picks up the b4A app and will backup it up to its backup directory. I haven't tried to reinstall one but I can't see why it won't work, it seems like it might need a different Version number to recongise it as a new app. It doesn't need root,
