the clickwheel of my replacement ipod 5g is moving a little. i dont have to press it in any special way, it moves when you just scroll with the clickwheel. thats quite annoying...when you change the direction your are scolling, you can feel the clickwheel moving a little in the same direction. theres not much space it is moving in, but it moves quite easily... just by changing the scroll direction. should i send it in once again? are your clickwheels moving, too?
