Apple posted the fourth beta version of iPhone OS 3.0 in the iPhone Developer Center yesterday, exactly two weeks after its previous release. In order to get access to the 3.0 beta software you have to be a registered iPhone developer.
Little information has been released about the new beta but there are a bunch of comments under stories at MacRumors and Engadget that are worth a peek.
The release, labeled build 7A300G, arrived exactly two weeks after beta 3. What does that mean? No much other the fact that Apple is working really hard on OS 3.0 and is trying to get all the bugs squashed in time for the June 8 announcement at WWDC. Oh, and we'll probably see beta 5 around 12 May.
Update: A MacRumors forum poster discovered references to Blu-Ray data from Gracenote in the latest iTunes 8.2 beta implying that support for Blu-Ray may be in our not-too-distant future.
