I bought iphone4 4 momth ago. Two weeks ago, I found light blue spot on iphone. Spot size are width 5mm height 15mm , located on middle left. Lastweek, I visited apple as center located in technomart , seoul. korea. Staff took a picture for iphone spot and sent email to apple center. Because the cause of sopt is whether user's fault or not. Yesterday I called from as center. He told me the spot was made my fault. If my fault, only finger touch on screen. I think it was absurd treation of apple policy. please help me. What can I do for this action of apple?
