iOS 4.2 goes gold, available now to developers

Hopefully, we'll soon see it in iTunes!
The iPad's ticket to multitasking freedom -- better known as iOS 4.2 -- has moves past the beta phase and onto GM, which means retail units should be seeing it soon. Besides the iPad, Apple is also providing builds for the second, third, and fourth generations of the iPod touch, along with the iPhone 3G, 3GS, and 4... so if you've got a friend with an iPhone Developer Program subscription, now would be a great time to get cozy.
Apple made some last minute tweaks that give fast access to brightness and volume controls right in the multitasking bar in addition to modifying the AirPlay icon (pictured after the break). Apple's also on the verge of allowing MobileMe service logins using an Apple ID.
