iOS 4.2 beta 2 arrives with iTunes 10.1 test
Apple tonight posted both iOS 4.2 beta 2 and a new, first beta of iTunes 10.1 to the Developer Center. It's unclear what the two provide besides bug fixes, although iTunes 10.1 is said to support some level of printing and is likely needed to make a computer an AirPlay target. More details are expected soon.
The release comes roughly in line with Apple's typical timeframe of releasing betas every two weeks, as the first beta arrived September 15. Apple officially promises a finished version in November for the iPad, iPhone and iPod touch and will supply AirPrint to every device as well as the first iOS 4 features for the iPad.
