New Features In iPhone OS 4

The Apple event just ended and Apple has announced the highly anticipated iPhone OS 4. First and foremost the new OS introduces multitasking. Apple has made sure that multitasking is not a big battery drain or a resource hogger. The application running in the background will have access to only seven selected services. This basically means applications which need any of these seven services can only support multitasking.

The Home button is used to switch between the running applications. Another major change in the iPhone OS 4 is the upgraded version of the Mail application. Sadly, except for the iPhone 3G and the iPod Touch 3rd generation, no other models support multitasking.

The Mail application now features a unified mailbox, along with threaded email conversations. Users can now also download attachments and open them via applications from the App Store. A good piece of news for the Corporate users is that they can now set up more than one Exchange account setup. Apple also announced the iBooks application for the iPhone. The iBooks application has been a huge success on the iPad and thus Apple has released an iPhone compatible version of it.

Another good piece of news for the Corporate users is the support for Exchange Server 2010, SSL VPN support. Developers can now also encrypt the data present inside the application for more safety. One of the lamestfeature of the new iPhone OS 4 is the home screen wallpaper. The OS also brings Game Center a service which targets the likes of Microsoft Xbox Live service.

The major tentpolefeature of the iPhone OS 4 is the iAd platform from Apple. This platform will allow developers who publish free applications on the App Store to earn some revenue. The iAd demo from Steve definitely looked interesting. An interesting thing to note about the iAd platform is that it uses HTML5 instead of Flash.

Other notable features include the ability to create Folders, 5x digital zoom, Create Playlists, Bluetooth Keyboard and Persistent Wi-Fi even in sleep mode. Except for the iAd platform, the iPhone OS 4 does not introduce any innovative feature. Everything Steve Jobs introduced in iPhone’s OS 4 today, is already being done by other mobile phone operating system present in the market.

A developer preview version of the iPhone OS 4 is already available at The iPhone 3GS will get the iPhone OS 4 update this summer, while the iPad will get it this fall.
