Apple today ready to announce the latest version of their software upgrade that is iPhone 4 called iOS 4 which will be available for download latterly by today on the web. The pre-requisite for iOS 4 is, the user must have an upgraded iTunes i.e iTunes 9.2 installed.

At once you have installed iTunes 9.2 just create a backup of your iPhone to iTunes, right click under your menu and hit backup. Just get ready with your backup now as when iOS 4 will be official in couple of hours. iOS 4 will be easily upgradable with iPhone 3GS/3G, although you may not be able to experience all the features but something is better to with nothing

iOS 4 is a complete multitasking system which lets you run multiple applications at once. Just stick yourself with the web as we will inform you guys as soon as iOS 4 gets into action.
