Think your iTunes installation is up-to-date? If you haven’t run Software Update since last week, chances are it’s not — the system administrator’s work is never finished. Slurp it down automagically or install the old fashioned way, it’s ready and brings some iOS 4.3 specific goodness you probably need.

iTunes 10.2.1, download
— Sync with your iPhone, iPad, or iPod touch with iOS 4.3.
— Improved Home Sharing. Browse and play from your iTunes libraries with Home Sharing on any iPhone, iPad, or iPod touch with iOS 4.3.
— Also available for Windows (64 bit)

Also, don’t forget to download Java for Mac OS X 10.6 Update 4, too — Java for Mac OS X 10.5 Update 9 for you Leopard users.
