iPhone OS 3.0 beta 2 build 7A259 released

The new iPhone 3.0 build opens up push notifications to developers in the SDK, allowing them to write code for in-game purchases, and obviously push notifications. Apple has also reportedly fixed several bugs and made the OS more stable, allowing it to run just that much faster. With my short term experience with it, it is actually a usable beta now. My iPhone has not crashed in the three hours I have been running the 7A259 build.
