The delayed iOS 4.2 firmware will finally be released later today, Apple has announced. No specific time has been pegged. The firmware is the first version of iOS 4 to reach the iPad, and makes several feature upgrades, such as support for streaming music, photos and video to an Apple TV via AirPlay, and printing to a handful of HP printers by way of AirPrint. Apple notes that greater printer support and AirPlay-compatible speaker options are expected over the course of the next several months.
