One week ahead of Worldwide Developer Conference 2009, Apple releases iTunes 8.2 and QuickTime 7.6.2.
iTunes 8.2 and QuickTime 7.6.2 are available for Mac OS X (Tiger and Leopard) and Windows (XP and Vista).

Early preview version of iTunes 8.2 was required to install iPhone OS 3.0 Beta 4 and Beta 5. Since then, no new iPhone OS 3.0 Beta has been released. It is estimated that iPhones OS 3.0 Beta 5 would expire sometimes late June 2009. That means a new build of iPhone OS 3.0 should be release in the near future. Possibly to coincide with WWDC 2009. The shipping version of iPhone OS 3.0 is expected to be released in mid-July along with the new iPhone hardware(s).
