My iPod nano 2 GB 1st Gen is doing something weird, and has been for awhile now. As soon as I eject it from iTunes and unplug it, the Play button doesn't immediately work. I'll hold it down to shut off the iPod until I need it, but nothing happens and the backlight shuts off, and then the backlight goes back on as soon as I let go of the button. This usually goes on for at least 20-30 seconds. Also, I've noticed that certain songs cause different little effects. Sometimes the forward/backwards buttons don't respond right away, sometimes they take a little longer to switch to them, and sometimes they causes a very visible delay in the backlight turning on (it really looks sluggish).
I bought it at the Radioshack I work at and I have a service plan, so should I try to get a replacement or at least try another repair? I've sent it in before for what I thought were battery problems, and if I remember correctly, last time they actually claimed they had to replace the hold switch.
