WWDC 2010 Dates announced

Apple has finally released iOS 4 – its eagerly awaited next generation iOS.

Apple had given us a sneak peak of its next generation iPhone OS in April.

iOS 4 includes over 100 new features for iPhone users such as multitasking, folders, better mail app etc and more than 1500 new APIs for app developers. 

So let's take Apple's new iOS 4 for a spin to find out the new features.

iOS 4 is now available as a free upgrade to iPhone 4, iPhone 3GS, iPhone 3G, second and third generation iPod Touch users.

Here is the long list of new features in iOS 4:


iPhone users will finally be able to run iPhone apps in the background. To achieve this Apple is offering developers seven multitasking services, which will allow their iPhone app to run in the background while preserving performance and battery life. We’ve started seeing multitasking enabled iPhone Apps available On The App Store since last week.

Unfortunately, the multitasking feature is available only to iPhone 4, iPhone 3GS and the third-generation iPod Touch (32GB and 64GB models from late 2009) users.


Users can organize iPhone apps on their iPhone home screen into folders. Users can also drag and drop apps into folders.

This means iPhone users will be able to install 2160 apps instead of the current limit of 180 iPhone apps.

When any of the apps inside a folder receives an alert, you'll be informed of the same with an exclamation point over the main folder icon.

However, nothing describes this feature better than the video below. The video also gives a demo of the multitasking feature, which shows how you can close apps running in the background.

Better Mail app:

You will now be able to see messages from multiple email accounts in a unified inbox.

You can organize emails by thread in the Mail app just like in Gmail. Email threading option can be turned on or off via Settings -> Mail, Contacts, Calendar and turn on or off the 'Organize By Thread' toggle (this feature was demoed during the iPhone OS 4 event, the screenshot shows you how it can be enabled).

Our Verdict

We really like the update, especially if you’re an iPhone 3GS, iPhone 4 or third-generation iPod Touch user and have access to all the new features. Features like multitasking, folders were some of the most requested features but the manner in which Apple has implemented them is quite brilliant.

We believe the combination of Apple’s new iPhone 4 and iOS 4 will be very difficult to beat.
