Apple's new firmware.

Yesterday Apple released its new firmware iOS4, which enables recent functions. But the most important innovations are the Multitasking and the Folders function.

Multitasking allows us to run apps and switch between them instantly without slowing down the performance of the foreground app or draining the battery unnecessarily. Authorized for multitasking are for example navigation-applications as well as audio streaming services or VoIP-Clients. But currently this is slightly problematic due to most producers have not updated their applications yet.

A folder in iOS 4 is a group of apps you access by tapping a single icon on your iPhone’s Home screen. When you tap a folder, which sports an icon that includes miniature versions of the icons of the apps inside, along with a name intended to describe the folder’s contents the dock fades and slides down, and the main Home-screen area fades and slides up to make room for a view of the folder’s contents. This view shows the name and full-size icon of each app. Tap on any app to launch it, or tap anywhere outside the folder area to close the folder and return to the Home screen.

Other notable new features are Spell Checking, a built-in dictionary, which automatically suggests words and corrects spelling. IBooks, a great ebook reader, which is also a place to browse and shop for books. And finally the possibility to create a playlists right on your iPhone.

But you should also know that many users claim that they met with several problems updating their software. Most of them complain about crashes when opening the photo album or apps. Moreover they had problems to backup their data. Nevertheless the free software update for the iPhone or iPod Touch can be found and installed on iTunes.
