iTunesApple just released iTunes 9.2, which comes with a few new features necessary before next week’s release of iOS 4 to ensure compatibility between this firmware and the devices.

iTunes 9.2 features and improvements include:

  • 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

Jailbreakers and people who plan to jailbreak their iPhones or iPads should stay away from iTunes 9.2 for the time being.

According to the Dev Team, Don’t install today’s iTunes 9.2 if you plan on using Spirit for fresh JB (but it’s fine for PwnageTool & redsn0w users).

If your iPad has already been jailbroken with Spirit, then everything will work fine. If however you plan on jailbreaking your iPad with Spirit, it will be caught in a boot loop.
