I am on my second 16GB ipod touch. The first one I bought from circuit city and returned it within 7 days because it would play music and than randomly stop and go back to the main screen. They did not have a problem with it and were willing to replace it but they did not have in the store so thy refunded me. I then went to the walmart next door and purchased another 16 GB ipod touch. I did not buy walmart's warranty. It has been 20 days since my purchase and the ipod is doing the same thing again. I went back to walmart but they would not let me even exchange it since it has been past 15 days. Can I take it back to an apple store and have it replaced or my money refunded? Is this a normal problem with the touch? Is there anyway to fix it or any plans to fix it?
