Apple today renamed its mobile device operating system, replacing the former iPhone OS moniker with “iOS.” Apple CEO Steve Jobs announced the change during his WWDC keynote address, and used the opportunity to highlight some of iOS 4’s previously revealed features, including multitasking, folders, the unified Mail inbox, rotation lock, and enterprise features like Exchange Server 2010 support, wireless app distribution, mobile device management, data protection, and SSL VPN support. In an update on the new iAd advertising service, Jobs mentioned a number of large brands that have signed on to the service, including Nissan, Citibank, GE, Sears, Target, Best Buy, and others; the service will go live on July 1 for all iOS 4 devices, with $60 million committed for the second half of 2010.
New to the OS will be an option to use Bing search instead of Google or Yahoo!; Jobs also revealed that the 100 millionth iOS device will be sold this month. Developers can download the gold master of iOS 4 beginning today by visiting the iPhone Dev Center; iOS 4 will launch on June 21 as a free upgrade for all applicable products, including the second- and third-generation iPod touch, iPhone 3G, and iPhone 3GS.
