I have started having a problem with my 3g 20gig Ipod. recently it has seemed to have lost sensitivity on the touch buttons, It can take several tries to try to get it to recognize the touch. Also, frequently if I am playing a song and then try to go back to the playlist to get to a different song, all the song names are blank and they will not appear again unless I go entirely out to the main menu and then back again. I have tried resetting the Ipod and not change and I have tried cleaning the ipod buttons to fix the touch sensitivity problem. Any other suggestions? Should I try to send it back to Apple, it has the one year warranty and I bought it in May.
