My iPod 4th gen. fell on the concrete and the glass screen cracked pretty bad.. How would i go about fixing it and what places are trustworthy sites to buy parts these days??? It's a black ipod but I figured why not make it white while I'm at it. So i guess what I'm asking is, where should I go to get both the white glass for the ipod, a new white home button, and what procedure should I follow when going about the switch?
