We've already given you plenty of reasons NOT to upgrade to iTunes 9.0, primarily if you've got a jailbroken iPhone. But if you're an average, everyday "I just use iTunes to update my iPod Classic, honest!" type, you've probably taken the plunge and loaded up 9.0 at iTunes' request.
For that reason, alone, you should answer "yes" when your computer asks if you want the iTunes 9.0.1 update. As per the minor version number, it's basically a bug fix that addresses the following issues:
- Resolves issues browsing the iTunes Store.
- Addresses a performance issue where iTunes may become unresponsive.
- Fixes a problem where iTunes may unexpectedly quit.
- Fixes a problem syncing Podcasts in playlists to iPod or iPhone.
- Fixes a problem sorting albums with multiple discs.
- Addresses an issue with the Zoom button not switching to Mini Player.
- Improves application syncing for iPod touch and iPhone.
- Genius is now automatically updated to show Genius Mixes.
If you haven't gotten the update prompt yet — or your home system's on a slow Internet connection and you bag your software upgrades elsewhere — you can bag the iTunes fix directly from the House of Jobs.
