Apple has released system software upgrades for the most recent iPhone and iPod touch models. iOS 4 adds much greater support for multitasking, as well as a range of other new features.
“iOS” is the new name for the iPhone OS. This change was made to better reflect the fact that this operating system is the basis for non-phone devices, including the iPad and iPod touch.
New in iOS 4.0
Easily the most significant new feature in Apple iOS 4 is much greater support for multitasking, which will allow third-party apps to perform some but not all their functions in the background, such as streaming music or downloading files.
In addition, folders have been going to be added to the application launcher, allowing users to more easily organize their software.
The latest version of Apple’s mobile operating system also includes a social networking service for gamers, and the iBooks app that debuted with the iPad has been extended to the iPhone and iPod touch. In addition, users can now enter text with Bluetooth keyboards.
Free Upgrades for (Almost) Everyone
Naturally, the iPhone 3GS and iPod Touch (Gen 3) can be upgraded to iOS 4, and this is free for both smartphone and handheld customers.
The older iPhone 3G and iPod Touch (Gen 2) can also be upgraded to the new version of this operating system, but the slower processors on these device mean they won’t support multitasking.
The original iPhone and iPod touch released in 2007 won’t get any more operating system upgrades.
To perform the upgrade to iOS 4.0, connect the smartphone or handheld to a PC or Mac running Apple’s iTunes desktop software.
