GPS Navigation Multi-Tasking in iOS 4 Demonstrated by Navigon

Navigon has been offering iPhone users turn-by-turn navigation for quite some time, but the issue is that when navigating with navigon, you will not be able to listen to the voice guidance during any phone calls. This causes problem for users who are driving and wish to talk on the phone at the same time.

With iOS 4 Multi-Tasking feature, Navigon can now navigate, and receive call at the same time, and after the call, Navigon application will automatically switch back to the foreground and resume full navigation with maps.

iOS 4 will launch on 21th of June,  3 days before the launch of iPhone 4, although most iPhone and iPod generation will be able to upgrade to iOS4, but only iPhone 3GS and iPod 3rd Generation will be able to enjoy the multi-tasking feature together with iPhone 4.

So, what do you think ?
