I have an IPad 1. It's in good condition, runs well but is slow and kicks me out of programs sometimes. Will keep this one but I will upgrade soon to the Air. Recently while in Notes adding info to one file/folder, everything before me disappeared except 3 or 4 folders. I lost a lot of info most precious the running observations of my granddaughter. Went to iTunes on computer - no Notes. Backed up today and now down to just 1folder. What happen? Where did everything go?
