Apple’s new upgrade of iOS 4.0 software for Apple iPhone works with iPhone4, iPhone 3 GS, and iPhone 3G. Not all features are compatible with all devices. Multitasking (only available with iPhone 4 and iPhone 3 GS) does not hinder performance of the iPhone. iOS 4 is a free update. The OS contains one hundred new and upgraded features. Now there’s much finer-grained control over apps and data. Now it will be easy to see what apps are running on the iPhone and how much storage remains. Users experience better organization and easier access through the use of separate folders. iOS 4 will be able to manage up to 2160 applications on a device and folders feature handy-dandy drag-and-drop. Email can now be viewed from all of your accounts in a single inbox. Attachments will open in a new, easier way.
