I returned my 4th ipad today. I had it for 14 days, had it on continuously, you know the whole nine yards. When they ask why are you returning it and you explain the yellow screen, I keep getting employees who answer like this is the first they are hearing of it. Is it me, but I thought this was pretty widespread. Did they do this to you? When I returned my others, not at apple store, they also denied hearing anything about it. Was curious what your experiences were. Thanks!!
