Apple iOS 4: 10 best features

Multitasking might be the biggest news in the latest version of the iPhone OS, but it has plenty of other useful features and refinements, too. Here's a hands-on look at our 10 favorites.

The Messages app in iOS 4 has also received a few welcome updates. For example, you can now search through your old text messages by pulling down the main message timeline.

The character-count feature is not enabled by default, though; you have to enable it manually from the Settings/Messages menu.
