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.
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.
- Beta 1 (7A238J) was released on 13 March
- Beta 2 (7A259G) was released on 31 March (18 days later)
- Beta 3 (7A280F) was released on 14 April (14 days later)
- Beta 4 (7A300G) was released on 28 April (14 days later)
