iOS 4.2 for iPad: What's new, detailed and explained

Yep, it was the big bonus in iOS 4.0 on the iPhone and iPod touch and soon iPad users will be able to appreciate it as well which might be fun now that enough developers have rewritten their apps to actually make use of it. Double tap the home button and it'll come up with a list of recently used apps which you can choose to close or go back to.

Before you get too excited, you can't multitask with absolutely everything but, if it has something to do with VoIP, audio, location, push notification, local notification, task finishing or just a way to quickly switch between apps, then you're in luck.

As it is on the iPhone and iPod touch, so shall it be on the iPad. This time the folders system will be brought to the Apple tablet with the iOS 4.2 upgrade. Folders allows you to clean up your app grid somewhat by creating, you guessed it, folders where you can drag and drop your icons. Press and hold on the screen to start your apps jiggling at which point you can drag and drop them where you want. The clever part is that your iPad will start to automatically place your apps in the right folders on download if it recognises them to be part of other similar groups.

Printing from an iPod touch or an iPhone might not seem quite as important but, given that you're supposed to be working on iPads as well as playing, sending sheets over a wireless network is a welcome addition. The Print Center app can be called up at the bottom dock on the iPad and you can choose where, how and how many pages to print from there.
