iPhone OS 4.0: First Video Walkthrough Of Multitasking

iPhone OS 4.0

One of the major features announced in iPhone OS 4.0 is multitasking, which will finally allow users to run third party iPhone apps to run in the background.

Steve Jobs said “We weren’t the first to this party, but we’re going to be the best. Like cut and paste — it’s better than any other implementation.”

You might remember that Apple had released the Push Notification service in iPhone OS 3.0 as workaround to multitasking as it had concerns on the negative impact on iPhone's battery life.

But Apple has managed to address this concern in iPhone OS 4.0. Apple explained that they’ve distilled the services that apps need to run in the background and have implemented those services in iPhone OS 4.0 and are providing those services as APIs to developers so that they can add multitasking support in their iPhone app while preserving battery life.

The seven multitasking services available to developers are: background audio, voice over IP (VoIP), background location, push notifications, local notifications, task completion, and fast app switching.

Here is a demo video of how multitasking will work in iPhone OS 4.0:

Apple’s implementation of the multitasking looks very good. Unfortunately as we've mentioned in our earlier posts, the multitasking feature will be available only to iPhone 3GS and the third-generation iPod Touch (32GB and 64GB models from late 2009) users.

Steve Jobs clarified in the Q&A session that Multitasking won't be available on iPhone 3G and iPhone 2G as the hardware just couldn’t support it.
