how to update ios 5.1 to 7
My daughter had a used ipod touch given to her. I am trying to set it up now. Trying to download games for her but when they go to install, it says it is not compatible with the version of ios. Says it is ios 5.1 and that it is up to date but the apps need version 7 or higher! I have tried everything I know to do with no solution
iPod touch, iOS 5.1.1
