I have a really strange problem with my ipod touch. It randomly opens apps when the screen has not even been touched. It will change songs on it's own or go into settings and actually change them. It changed the language from English to Spanish which as frustrating as it was it was also quite funny. The screen is also unresponsive intermittently. It has gone into an apple service centre to be looked at. I have heard of others who have had unresponsive screens but have never come across anyone in any forums who have had the problem of the touch opening apps on its own.
