Lock the screen orientation

The iPhone 4's operating system represents a significant improvement on earlier versions of Apple's smartphone operating system. It's also got a new name - iOS - signifying the importance of the iPad alongside the iPhone.

And what's more, iOS 4 is available to users of the iPhone 3GS, third-gen iPod touch and 3G too (albeit with limited features with the latter). iOS 4 will be available for the iPad later in the year.

Lock the screen orientation

If you're lying in bed reading an iBook or a page in Safari it can be annoying when the iPhone's orientation keeps flicking between portrait and landscape. You can solve this by activating the new Portrait Lock. Double tap the Home button to reveal all the running apps, then swipe your finger to the right to reveal iPod controls and the Portrait Lock.
