Apple’s [AAPL] latest version of their iPhone OS, now called iOS 4 will be available to download later today. In order to install iOS 4 on your iPhone or iPod Touch you will need to download the latest version of iTunes, iTunes 9.2.
Once you have downloaded the latest version of iTunes, make a manual backup of your iPhone in iTunes, right click on your iPhone in the menu and press backup.
