Version 7.0 brought a dramatic redesign of iOS with a new font, flatter icons, a and new Photos app. IOS 6.0 removes Google Maps in favor of Apple Maps and added the Passbook app (now known as Wallet). IOS 5.0 introduced Notification Center, iMessage, Siri, and iCloud. The major features were multitasking and FaceTime. In version 4, Apple finally renamed iPhone OS to iOS (with the iPad sharing the same software). Version 3.0 was released in 2009, and it included copy/paste, MMS support, Spotlight, mobile tethering, and push notifications for 3rd party apps. In the summer of 2008, Apple added the App Store to iPhone OS with version 2.0, and this set the stage for the “app economy” that we still enjoy to this day. When Apple launched the iPhone SDK a year later, they officially changed the name to iPhone OS. During the event, Jobs referred to the operating system as OS X because it shared a similar Unix core compared to the Mac. In 2007, Steve Jobs introduced the iPhone and iPhone OS.
