Hot on the heels of the release of OS X Mountain Lion 10.8.1, Apple has seeded 10.8.2 to developers, and it includes a couple of interesting features. With 10.8.2 should come the built-in Facebook integration that Apple promises will come to Mountain Lion this fall. In addition, iMessage phone number merging appears in 10.8.2 as well, a feature that will allow users to receive iMessages sent to their phone numbers on their Macs, iPads, and iPod touch devices. Apple asks developers to also focus on Game Center and Reminders in the first 10.8.2 build 12C31a.
