IOS is 4.0 to remove all my iPod Touch?

I'm buying an application in the App Store on my iPod Touch (iGir). I'll buy it and said, my iPod: "Implementation is not supported This application requires the iPhone 3.1.3 Software Update, I click" OK. " "I can connect my laptop on my iPod, open iTunes, sync and transfer my purchases. I click "Update" to update my iPod. I get this message: "Update 4.0 IOS will delete all media, including purchases from the iTunes Store. To keep the media, to apply this update the computer when you sync music, videos and photos. Update on that computer only preserve the applications, contacts, calendars, text messages, and other parameters. Do not interrupt the update, that's my take an hour or more to complete. iTunes Software Update checks Apple. "I am very confused about what to do. I have an iPod Touch version 3.1.2. I can not update anyway? What will happen to all my music and applications and all?

Yes, you have to update anyway (in my opinion) because the message is all that is that the new software must be installed the program should delete all of your iPod. But if it continues update, and then after all done and installed iTunes asks if you want to use as a new iPod or synchronize the backup (regardless of iPod is called) then put the iPod and click continue and we must put all your music again. It should also be able to download the application you tried to download!
