Apple has posted an iOS 4 Apps section on the iTunes App Store, which is also accessible from the Featured section on the iPhone’s App Store. Currently there are 42 apps in the section, all of which utilize iOS 4’s unique features in one way or another, many taking advantage of iOS 4’s new multitasking and fast app switching capabilities.
Some of the highlights in the ‘iOS 4 New Features, Awesome Apps’ section include Apple’s own iMovie, Evernote, and Dropbox. You can expect many more apps to fill up this new category in the near future as developers submit their iOS 4 specific apps. Of course the majority of the apps featured in this section are only compatible with iOS 4 devices and higher.
