i had a 2nd gen touch and i dropped it in the lake while fishing, lol. big mistake. i got it home and it worked ok. then my speaker stopped working. so i turned it off and put it in rice. i tried using it 2 days later and the touch screen stopped working. i took off the screen and accidentally cracked it. i was wondering if my digitalizer or whatever its called stopped working? should i buy a replacement screen kit? or is it not worth it?
