If you have paid your $99 and have access to the development kit for iPhone, then you can now get the most recent update. The iPhone SDK 3.0-Beta 4 and iTunes 8.2 Pre-Release are now available. While we do not have a lot of details regarding the updates, we do know that in order to activate the iPhone 3.0 Beta 4 firmware you must already have iTunes 8.2 installed. We will be sure to update you of any significant changes should they come our way.
[UPDATE] According to a post on MacRumors
"One forum poster points out that the latest iTunes 8.2 beta carries references to Blu-Ray data from Gracenote, suggesting that iTunes could support the reading/recognizing of Blu-Ray discs. This note is not present in the current version of iTunes"
