iPhone 3.0 beta 2 released, push notifications are a go

The rest of the mobile industry might be gearing up for CTIA to start, but Apple's phone elves are toiling away -- iPhone OS 3.0 beta 2's just been released to developers, along with the go-ahead to start developing for push notifications. Thankfully, beta 2 also apparently includes a number of stability and performance enhancements, which will hopefully make our tester phone tolerable again -- we've been restarting beta 1 basically every day since we sacrificed it to the hands-on gods. Devs and beta testers know what to do to snag the upgrade, let us know how it goes!
