The long awaited iPhone OS update will be presented tomorrow in a special event initiated by Apple.

The next version of the software is the iPhone OS 4.0 and rumors claim that the most important feature of this new update will be the multitasking which may work the same way Expose works on Mac OS and it will be available for the first time for third-party applications.

Another aspect about the new iPhone OS is that some features from the Apple’s iPad could be added to the iPhone OS, including the ability to customize the background wallpaper using the iPhone in any orientation you want. Also, it is possible to see a merge between the iPhone OS and the iPad OS later this year which will be the iPhone OS 4.1
