I am not entirely sure either what answer to your question you are referencing. It doesn't look like you've posted here in our forum regarding this before. Did you ask this question of us somewhere else?
Our StudyBlue mobile app is compatible with iPod Touch devices (not the generic iPods) unless yours is a first generation iPod Touch. You should be able to go to the app store in iTunes and download our app for your iPod Touch without problem.
Let me know if you have any other questions.
