With the iPad’s imminent arrival, we knew it would be coming, and now it’s here: load up “Software Update” now to slurp iTunes 9.1 down to your Mac. The update weighs in at 102.1MB.
As reported, the changes involve the addition of a “Books” category, some improvements to the way Genius Mixes are handled and the new, universal ability to downgrade songs on the fly to 128kbps AAC when transferring them to your device in order to save space… function previously limited only to the iPod Shuffle. Hurrah!
The only real thing to watch out for here? Some users are reporting issues syncing iTunes 9.1 with their jailbroken devices. The issue seems to be rare, and may be solved by a reboot, but if you’ve got a jailbroken iPhone, you might want to be wary here.
