iTunes 7.3 unexpectedly, shockingly available

Wow, this is so completely surprising! iTunes 7.3 is out now, and the 33.8 MB (Mac version) download offers new features including... well, including what we all knew was coming. Good luck to everyone standing in line trying to work off nearby WiFi to get the new version.

Update: Comments have pointed out that in addition to the iPhone support, this update also fixes longstanding Coverflow problems on the MacBook, and adds wireless photo sharing from multiple computers to AppleTV.

Thanks, mentalsticks.
