iPhone US 4.0

The much awaited iPhone OS 4.0 is on its way. There are quite a few new features added to the new OS. Here are some of the major new features:

• Multitasking - The biggest request from iPhone users is the ability to multitask, and Apple delivered. Part of the new operating system includes a quick way to switch between applications without losing your spot in any of the open apps. Services include background audio, so apps like Pandora can play music in the background.

• Better Background Support – for example, you're using an iPhone for turn-by-turn directions and need to check an email while still on the road. Now you'll be able to without killing the nav app.

• Folders – Another wonderful feature which allows you to organize your iPhone apps in folders.

• Email Improvements - It will gain a unified inbox and it will also support threaded email conversations.

• Game Center - As part of iPhone OS 4.0, the iPhone will support a more social gaming experience.

• iAd - Apple debuted its new mobile advertising platform. No one really like the way ads work on the iPhone. When you're playing a game, there's nothing worse than accidentally clicking on an in-game add that closes the game, opens the browser, and sticks you on a web-based ad.

Apart from these major features, there are plenty of minor features which you might want to look out for.
