Apple Releases First iOS 4.2 Beta for iPad, iPhone, and iPod Touch
As noted by CoveringWeb, Apple has pushed out to developers the first beta version of iOS 4.2. At its media event on September 1st, Apple announced that iOS 4.2 would be released in November and would unify iOS across Apple's mobile devices, bringing iOS 4 features such as multitasking to the iPad for the first time.
Soon after the media event, Apple posted a preview page showing some of the features coming to the iPad in iOS 4.2, including the multitasking and folders already available in iOS 4 for iPhone and iPod touch but also such features as printing and AirPlay support for streaming media from the iPad.
Coming just a week after the public launch of iOS 4.1 for iPhone and iPod touch, the initial iOS 4.2 beta is available for iPad, iPhone (3G, 3GS, and 4) and iPod touch (second-, third-, and fourth-generation).
Update: Users are reporting that the AirPrint feature in iOS 4.2 beta also requires that users install the latest Mac OS X 10.6.5 beta. The Mac OS X beta has reportedly been made available to developers in the iOS Developer Program for this purpose.
