Apple, after releasing the iOS 4.2 beta Gold Master version of its mobile operating system, is now accepting apps for the App Store that have been tested against iOS 4.2 GM and are ready for public release.
Apple will begin reviewing submissions from developers so that the store will have plenty of iOS 4.2 apps available when the new operating system releases later this month.
The GM version of iOS 4.2 beta also includes a few minor changes that were not in the previous beta release, including a redesigned multitasking bar that adds easy access to volume and brightness controls. The multitasking bar also includes a button for AirPlay.
iOS 4.2 will also allow people to log in to MobileMe services using their Apple ID account name and password.
One of the big issues that will surely cause controversy in the Apple mobile world is the repurposing of the hardware switch on the side of the iPad from being a rotation lock to a mute switch in iOS 4.2. Currently there is no toggle for this functionality in iOS 4.2, but don't be surprised if it's added at the last second, given the response from many users.
Developers should build, test, and compile their apps using iOS 4.2 beta Gold Master and submit them to Apple for approval. I would imagine being among the first for iOS 4.2-compatibility is good for business.
