Today, as expected, Apple unleashed the iOS 4 for the iPhone 3G and 3GS, as well as the unreleased iPone 4. Also, the iOS 4 will be available for download on the more recent iPod touches. To download the iOS 4 you will need to install iTunes 9.2. This is the only way to get all the new features available with the iOS 4. The brand new features exclusive to the iOS 4 include multitasking, fast app-switching, and local notifications. So iPhone and iPod touch users, head to iTunes and download it now.
