In preparation for next week's release of iOS 4 and iPhone 4, Apple on Wednesday updated its iTunes desktop media application to version 9.2, adding support for iBooks, PDFs, and Apple's latest handset.

iTunes 9.2 is available for download direct from Apple, or via Software Update on a Mac. It is a 101.99MB file for Mac OS X, 92.29MB for Windows 32-bit, and 92.99MB for Windows 64-bit.

Apple said Wednesday the update to iTunes includes the following features and fixes:

Sync with iPhone 4 to enjoy your favorite music, movies, TV shows, books and more on-the-go

Sync and read books with iPhone or iPod touch with iOS 4 and iBooks 1.1

Organize and sync PDF documents as books. Read PDFs with iBooks 1.1 on iPad and any iPhone or iPod touch with iOS 4

Organize your apps on your iOS 4 home screens into folders using iTunes

Faster back-ups while syncing an iPhone or iPod touch with iOS 4

Album artwork improvements make artwork appear more quickly when exploring your library

Word of iTunes 9.2 first arrived during Apple's Worldwide Developers Conference last week, when it was seeded to developers in a Golden Master form.
