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.
Digital zoom and geo-location for your camera
The Camera app in iOS 4 adds a 5x-digital-zoom slider above the shutter button. The slider is easy to access, but the pictures can get a bit blurry if you zoom in a lot (optical zoom is not available on the iPhone).
When you first open the Camera app in iOS 4, it asks you for permission to acquire geolocation data. You'll see this data in action in the Photos app, in a new feature called Places; your photos appear on a map based on where you took them.
The upgrades aren't limited to your still photos, either. When taking videos, you can now tap to focus on your subject--just as you do when taking photos.
Useful enhancements in native apps
Though the previous slides show the biggest changes in iOS 4, you'll find small enhancements in the native apps, too. For example, in the Safari browser, you can now choose from Google, Yahoo, and Microsoft Bing as your default search provider. The browser also displays word suggestions as you type in the search box.
Apple has bumped up the Notes app with wireless syncing, so now you'll always have your notes in sync. This feature works without cables, and it creates a folder in your inbox for over-the-air syncing.
If you keep birthday information with your contacts, you will be pleased to find that the Calendar app now has a place to store that data alongside your schedule. Lastly, heavy typists will appreciate the added support for most Bluetooth-enabled keyboards.
