Apple has released iTunes 10 as promised, and is now available for download to the public for Mac and Windows.
iTunes 10 includes Ping, a brand new "social music discovery tool" creates a new experience for iTunes where users can follow their friends and share their favorite music.
It appears that iTunes 10 is Jailbreak safe for now, that is to say that a new Jailbreak tool might not work with iTunes 10, but seeing as there are none out right now that require iTunes, your JailbreakMe.com exploit should be just fine. Musclenerd also informed us that we should be safe as far as DFU Mode, syncing, and custom IPSW's go, just stay away from iOS 4.1 next week.
