I sent my ipod touch 4 to apple because of light leaks and wifi issues (wifi doesnt hold after an hour of usage). The back is pretty scratched up and the screen has some scratches. I owned the ipod for 8 months. They told me they were still deciding whether to repair or replace it. Do you think they will just repair the inside and send it back to me with the same unit or replace it with a brand new/ refurbished?
