Apple has released the new iPhone OS 3.0 beta 4 7A300g along with the iPhone SDK 3.0 Beta 4 and is made available to developers. iPhone OS 3.0 Beta 4 is the 3rd consecutive alternate to beta 1. Before this release, many code divers discovered a lot of unannounced features in Beta 2 and Beta 3 of iPhone OS 3.0.
We can’t expect some great updates in Beta 4 and there are reports that developers need to install iTunes 8.2 Pre-release before installing iPhone OS 3.0 Beta 4. Like previous Beta releases, iPhone OS 3.0 beta 4 is intended for testers and developers only. Don’t install the beta if you don’t need it. NEVER buy it.
