Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Apple Wraps Up Push Notification Testing Ahead of WWDC
Apple activated Push Notifications in mid-April, allowing developers to begin testing their applications with the service, which allows iPhone applications to receive updates while they are not actively running. Apple's AP Mobile test, however, was the first large-scale deployment of Push Notifications.
The conclusion of Push Notification testing and yesterday's public release of iTunes 8.2 supporting iPhone OS 3.0 suggest that development of the new iPhone operating system is nearing completion. iPhone OS 3.0 is expected to be a major topic of discussion at Apple's Worldwide Developers Conference next week, and many expect to hear about Apple's plans for its public launch at that time.
