As of November 1, 2010, Apple completed the “golden master” version of its latest IOS update for the iPod Touch, iPhone and iPad. Version 4.2 is the first upgrade that will bring the functionality of IOS 4 to the iPad, and includes a number of new features that aim to make Apple’s range of mobile devices even more user-friendly.

Users can expect to see this version of the IOS within a week or two if previous releases are any indication, and app developers are now able to submit and tweak their apps for the final release version, meaning that most will be up and running when the upgrade hits.

From a proprietary Apple perspective, the most important advancements in this IOS are AirPrint and AirPlay. AirPrint will allow users to wirelessly send documents to printers, while AirPlay will allow them to transmit music or video to a supported receiver.

At the moment, both AirPrint and AirPlay are fairly limited in functionality – the Print is focused on HP printers and the Play mostly on Apple TVs and similar devices, but this is merely the first iteration. Just as the iPhone and iPad IOS has become far more functional from 3 to 4 and now 4.2, AirPrint and AirPlay will also evolve.

For high-quality A/V users and those with cutting-edge home theatre systems, this means the ability to use their Apple device to wirelessly stream their favorite music or video is enroute.
