Apple ipod

My habit iPod Touch allows me to download applications, and I need to "iPhone OS "….?

My iPod Touch allows me to any request transfer because I need to "iPhone OS "….? I can not download a few applications because it keeps giving me the message (eg) "God's Pocket" has not been installed on the iPod "(my name)" because it requires a new version of iPhone OS. But it is an iPod, not an iPhone. It also costs $ 5. I will pay, but I prefer to be sure it works. Does the iPhone OS update work on my iPod Touch 2nd Gen normal? not have a microphone and other things. Ghost-

The update OS is running on the iTouch and it is necessary to use many of these applications.
