iOS 4, released yesterday with much fanfare, brings seven major, new additions to the iPhone fan base, and around 100 extra smaller improvements and tweaks. The major, new benefits iOS 4 brings, dubbed “tent-poles”¬ by Apple’s CEO during one of his recent keynotes, are Multitasking; App Folders; Enhanced Mail app; iBooks for iPhone and iPod touch; Enhanced enterprise features; Game Center; and iAd.
Multitasking, the most prominent feature in iOS 4, employs several methods (services) to allow applications to perform tasks in the background, while preserving battery life and performance. Those include background audio, Voice over IP, background location, push notifications, local notifications, task finishing, and fast app switching.
Apple has posted an iOS 4 Apps section on the iTunes App Store, which is also accessible from the Featured section on the iPhone’s App Store. Currently there are 42 apps in the section, all of which utilize iOS 4’s unique features in one way or another, many taking advantage of iOS 4’s new multitasking and fast app switching capabilities.
