Apple's latest operating system upgrade for the iPhone, iOS 4, was released Monday, packed with over 100 new features including multitasking and folders.




iOS 4 is compatible with iPhone 4, iPhone 3GS and iPhone 3G, as well as recent generation iPod touch. Multitasking is only available with iPhone 4 and iPhone 3GS. iOS 4 also comes preinstalled on the new, $99, 8GB iPhone 3GS, as well as the next-generation iPhone 4, set for release this Thursday.

* Even better Mail: See messages from all your accounts in a unified inbox, organize messages by threads, open attachments in third-party apps, and more.

* iBooks: More than a great ebook reader, iBooks is also an amazing place to browse and shop for books, day or night.
