iPhone OS 2 is the second version of the now renamed iOS operating system from Apple Inc. It was replaced by iPhone OS 3 on June 17, 2009 .


The most important innovation is the App Store , which makes it possible to install third-party apps on the iPhone or iPod touch . Before the release, Apple held a keynote to announce the iPhone Software Development Kit (SDK for short). The redesigned mail app now has push emails that are always active. The Contacts app has a new home screen icon, but it's only available on iPod touch. After the update to iPhone OS 2.2, Google Maps functions were added, for example Google Street View . Settings has been expanded to include functions, for example the ability to switch location services on or off or switch WiFi back on in airplane mode.
