iOS 4: Release Details

Source: apple.com – iOS 4

The iOS 4 is an operating system designed and developed especially for iPhone, iPod touch, and iPad by Apple from 2010 to 2011. The system was released on June 21, 2010, and was preinstalled on the iPhone 4, iPod touch 4th Generation, iPad 2, and Apple TV 2nd Generation.

The new operating system introduced folders on the home screen, significantly increasing the number of apps that can be displayed. Support for custom wallpapers was also added, although limited to newer devices due to animation performance requirements.

The operating system also added a multitasking feature, letting apps dealing with Internet calling, location, and audio playback function in the background, whereas a similar but more restricted “Fast App Switching” technology enabled any app to be left inactive in the background while users switch to other apps.

iOS 4 also added a system-wide spell-checking feature, enabled iBooks on iPhone, unified the Mail inbox to combine content from different email providers, and introduced both Game Center for social gaming and FaceTime for video calling.

This software got the last update (4.3.5) on July 25, 2011, and later has been replaced by a newer version of iOS 5. Today iOS 4 is 13 years old!
