As promised by Apple, iOS 4.2 is now available. Head on over to iTunes and download the latest and greatest iOS firmware to date. iOS 4.2 brings a huge number of improvements to the iPhone and iPod family and finally brings the iPad into the 4.x fold. It's a terrific update, and one, we think, that's been worth the wait.
Let us know in the comments how your upgrade went, and how you like the new release.
