Apple has just released firmware updates both for the iPod Touch and iPad. The iPod Touch now has iOS 4.02 and no mulit-tasking on the iPad yet. The update for iPad is 3.2.2 The only reason Apple had released this update was to fix a bug with the PDF and this patches the exploit. This was the same reason jailbreakme.com was made. But now if you do update you lose jailbreak and jailbreakme.com will not work. This is probably the only reason for the update. Nothing huge. In order to update you need the latest version of iTunes and then immediately once you plug in your iPod/ iPad. iTunes should recognize it and ask for update.
