Can I update to iTunes 9.0.2 with a jailbroken or unlocked iPhone?

Several new features for iPhone users have come to iTunes 9.0.2, now available from Apple as a free download. iPhone specific-improvements relate to app sorting and media syncing. Users can add or delete home screens and arrange apps directly in iTunes.
