Need help getting PDFs back into iBooks.

Hi, all.

I updated my iPad 2 to 5.0.1 and had to reinstall iBooks. Now my PDFs aren't showing up in the library, but iTunes says that I have 3.8 GB of "Other" files so I know they're still in there somewhere. Some were downloaded as email attachments, but the important ones were downloaded from Safari. Any help would be immensely appreciated. Also, I cannot use iTunes because I no longer have the computer that the iPad was originally synced to.

Thanks!

Although I could use iTunes after copying all of the PDFs onto this computer. Then it's just a matter of dragging them onto the iPad. I'm having a lot of trouble locating the PDFs in iFile though...

The PDFs are definitely not in /var/mobile/Media/Books

I'm thinking that iOS 4 used a different directory or location for storing PDFs.

Yeah, that's how I noticed that all of the PDFs were gone.
