made the mistake of starting off with my ipad 2 by building files through emailing pdf not itunes. using either ibooks or good reader and others if various files didnt open in either of those. if i replicate this will erase all that of the above. is there a 3rd party resource that can save most of these so i can upgrade to io 5? it might be simpler to just start over again with a new ipad( or windows os). some of these files will only print not export to another app.
It is not clear what app you have these PDFs in currently.
using both ibooks and good reader. if i replicate with itunes to upgrade it will clear everything out because it was brought in by email or download from websites not itunes.
I've never lost documents from within Goodreader or iBooks if I backup before upgrading, AFAIK. And I never sync documents to Goodreader by iTunes, either from my NAS or Dropbox.Quote:

BTW, you would be upgrading to iOS 6 because that is the current version, not 5.
why not connect your ipad to pc and transfer your pdf to the pc and when you need it you just transfer back the pdf to the ipad its easy no hassle :thumbs:
