Apple released the gold master version of OS 4.2 to developers late on Monday. The GM release is one of the final steps before officially unleashing the highly anticipated iPhone, iPod touch and iPad update on end users.
Apple is asking developers to start submitting apps and app updates built using iOS 4.2 developer tools so their titles will be ready when the OS update is released.
Apple is ready for iOS 4.2 apps
iOS 4.2 was first shown off during an Apple media event on September 1st with the promise of a November release. The update will bring multitasking, app folders, and other improvements in iOS 4 to the iPad, and it will also introduce AirPrint to both iPhone, iPad, and iPod touch.
The new update for iOS 4 will require Mac OS X 10.6.5 for sharing local printers with iPhones, iPads and the iPod touch, and will also require iTunes 10.1 which is currently available only as a beta for developers.
iOS 4.2 will be available as a free update for the iPhone 3G, iPhone 3GS and iPhone 4, as well as the iPod touch and iPad.
