    OK, I just went out and bought myself an iPod Touch 4G, and when I plugged it into my computer, and after I set it up, I noticed that the screen COMPLETELY wigs out when using it while its plugged in. Its like the calibration and targeting is off, as I can slide-to-unlock from the top half of the screen, and scrolling through home pages is completely messed up.

    As far as I can tell, its just the multi-touch, and everything else works fine (eg. home/sleep/volume buttons.

    I just wanted to know if anyone else had experienced this. I do have a theory that since the touch-screen senses the minute electrical charge in human skin, the charge from the USB cord may be messing with it.

    Any input appreciated

    I have this exact same problem, but with a wall charger.

    Hoping for a little insight.

    What you explained can explain the problem. But if you are using Apple's USB cable and a USB 2.0 (IDK if any computers have 3.0 yet) port, then it would most likely be the iPod malfunctioning... Bring it into Apple

    If you are using a wall charger, they sometimes spit more than 5volts out so this can cause electrical charges to be read. This is not a problem with the iPod, but the wall charger in most cases. To test if it's the iPod or not, plug it into a computer.

    I say get a replacement, that isnt normal.

    That doesn't happen to me; I have an Apple wall charger. I agree, take it to Apple.

    Happens to me with a legitimate iphone Wall Charger, but doesn't happen when i plug it into the computer. My suggestion, take it back and show apple about it.

    Wall charger is to blame... Exchange it. Can't be the iPhone, it functions well with PC, but not with wall charger. The only change is PC to wall charger.
