The iWork suite for the iPad has been updated to support the iOS 4.2 update, which should be available within the hour (1PM EST).
Those upgrading to iPad 4.2 will be happy to know that the latest update to the suite, which includes Pages, Numbers and Keynote, will add multitask support. Also reported to be in the coming update are improvements in the reliability of PDFs, and presenter-display support for Keynote. This means that when the iPad is connected to an external display, you will be able to view the current slide, as well as the next slide and your notes on the iPad's screen.
Along with the updates will come the minor fixes for bugs and compatibility issues. We expect the software to come today along with the launch of the latest iOS update.
