Apple has just seeded iOS 4.2.1 Gold Master to developers. This update has build number 8C148 and, according to MacStories, was just released internally at Apple last night. This update for iOS 4.2 may have been released in an attempt to squash last minute Exchange and audio-related bugs discovered earlier.

Just last week Apple released a second gold master seed for the iPad to address Wi-Fi related problems. The audio issues in iOS had been documented by several developers across several different devices on Apple's Developer Forums. Many developers noted that audio sessions were interrupted and not resumed when the device was locked and then unlocked.

At the last iOS-related Apple event, Steve Jobs told us that iOS 4.2 would be coming out sometime in November. To recap, iOS 4.2 will be bringing all of the iOS 4 goodies to the iPad. The rest of the iOS devices will also be getting the new AirPrint and AirSharing feature, which allows for printing directly from the iOS device and streaming to an Apple TV.
