I have several files stored onto Iannotate as im in university, my last itunes sync i accidentally deleted a file then synced. This file is absolutely crucial to my uni studies as it has ALL my data on a subject (Lectures, notes ect). My question is can i recover that file anyway? Ive tried restoring my ipad through itunes back up but it wont restore the past weeks which is the timeframe to which my file was deleted, any help would be greatly appreciated. Thank you.
