When I use the app transdeluxe a tanagram making game my iPod still puts out sound on the speaker even with the volume all the way down. I tried some of my other apps and they don't seem to have this problem but I'm wondering if it's just an app glitch or if my iPod touch is messed up. This app never used to dothis on my iPod touch 3rd gen but it started doing it with my 4th gen. Also one of my other apps is displayed upside down. That never happened with my 3rd gen touch. Could my iPod touch be glitching and need a replacement? All of my other apps seem to work fine.
