Long story short, my notes app (Smart Notes) lost all my notes suddenly today. Updated my iPhone4 to iOS6 about 1.5weeks ago.

My last iTunes backup is from 8 days ago. (I don't understand how to backup from iCloud and/or it is scary.) If I backup to that one from 8 days ago, and maybe email myself the important notes from the App, could I then "re-backup" to today's iTunes backup?

I fear staying in "8 days ago iPhone" and losing anything else I've done in the past 8 days that I've forgotten I've done. I just want to go back in time, copy my notes, and then come back to now. Possible?
