Apple Releases iOS4 For iPhone & iPod Touch

As promised earlier this month at its Worldwide Developer Conference, Apple has released iOS 4, the latest version of the operating system powering its iPhone & iPod Touch, with an iPad version out in the fall. Apple's free software update adds over 100 new features, including much-requested multitasking functionality for iPhone 3GS and third-generation iPod Touch devices. All hardware generations will be able to enjoy other features such as iBooks, playlist creation, app gifting, spell checking, and Bluetooth wireless keyboard support. A notable improvement for iPhone game fanatics is iOS 4's new Folders functionality. Users can now sort up to 2,160 applications in customizable folders, making it far easier to find your favorite games and utilities. Be warned that iOS 4's many changes will likely result in unexpected bugs and glitches for existing applications. Any potential issues will likely be smoothed over as applications update over the next few weeks, but in the meantime, be aware that many popular games -- including ngmoco's Eliminate Pro and Touch Pets Dogs -- may not work as expected.
