Evening, Ive had my Touch for nearly a year now & everythings been kushtie til lately. When i press the sleep button its irresponsive, then when i proceed to hit the home button, instead of taking me to the first page of apps, it takes a screen save. This started not to long ago & its annoying, because it can happen at any moment. What do i do? P.S: I still have about 4 months left on the year warranty.
