I have to say this: there is no way to backup your applications DATA unless you're rooted or are on Froyo 2.2. It's absurd. I came from Blackberry where literally everything could be backed up. On Android, you cannot, unless you have Froyo. I had to do a factory reset once and even though all of my apps were easily re-downloaded from the market, the data in them (high scores, passwords, notepads) was all gone.
Mybackup Pro is a waste of money as it installs your apps back onto the device after a restore but does not link them to market which makes it impossible to download updates for the apps.
I even asked Phil and Jerry about this on the podcast and they said there is no way. Titanium Backup is only for rooted users and I'm sorry, I shouldn't have to root to be able to backup my apps data.
