I had a beautiful bright white iPad 3 but a few dead pixels popped up,the closest apple store is over an hr away and I use the iPad as my only computer so I couldn't send in and wait for a replacement,so this last thurs,i had a drs appt in the city where the store is at and I made a reservation they exchanged,and I looked it over quickly,but didn't notice till I got home when I could be on it longer that I noticed how off white the screen is,my daughter brought her iPad 2 next to it,BIG difference hers is a bright white and mine looks dingy next to it,I read in a few places online that it was the glue and it would disappear after time,I checked the date this was made and it was the 2nd week of Jan so this is a new not refurb,should I just deal with it or exchange it again?
