Hello, please may someone tell me: Is it normal that every so often whilst listening to music, going on apps, internet on your iPod Touch, it goes back home automatically without actually pressing the home button? Will they exhange this for me if they don't fix this? Should I restore it before? Also, about the screens, if I do exchange it, will they give me a blue-tinted screen. My iPod is week 39 now, so is it yellow? There does not seem to be any difference. Please kindly reply as I am going to an Apple Store tomorrow and need to know these things. Thank You.
