Apple has released the fourth beta version of iPhone OS 3.0 to developers, along with an updated version of the iPhone software development kit (SDK), and a pre-release version of iTunes 8.2, which is required to activate iPhone OS 3.0. It is currently unclear what changes might have been made to the SDK, OS, or iTunes with this release; however, legal language referring to Blu-Ray data from Gracenote has been spotted in iTunes, suggesting Apple is working on Blu-ray playback/support for the media jukebox. The updated SDK weighs in at 2.13GB, and is listed as build 9M2734, while the iPhone OS 3.0 beta 4 is listed as build 7A300g.

Developers can download iPhone OS 3.0 Beta 4, iTunes 8.2 pre-release, and the accompanying updated SDK from Apple’s iPhone Dev Center.
