Apple's iPhone OS 4 - 10 best new features

There's more to iOS 4 than multitasking

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 favourites.

Unified Inbox and threaded email

If you have more than one email account set up on your iPhone, the unified inbox in Mail is a big improvement. The All Inboxes tab shows all of your email messages in chronological order, though you can't see from which of your accounts each message belongs to. You can set up multiple Exchange accounts, as well.

Email threading is also supported (the number of messages in a conversation appears alongside the subject), and when you tap a thread, you see the list of email messages within it. Additionally, anyone who receives attached documents will appreciate the new option in iOS 4 that allows you to open attachments in third-party applications.

Getting the right words

Misspelling words while typing on the iPhone's small on-screen keyboard should be less troublesome with iOS 4. The update introduces a system-wide spelling checker that extends both to native apps and to third-party apps (at least the ones we tested). You also get a new cut-and-paste option that lets you replace certain words with the clipped text.
