Hi, I'm having problems with my ipod touch 2g since I bought it, most of the buttons (slide to unlock...) are not right. the "slide to unlock" bar is looking like it is broken. The cover flow is also weird, when I flicker the albums with my finger the reflections on the ground are flashing. And at last, in the settings menu the background is weird : there are many vertical stripes. How can I fix this ?
