Just bought my new iphone 3GS 16G this afternoon at an apple store in UK. the pay as your go version which cost me £450 When trying to install the screen protecter back home, I find the same old 'dust in the screen' problem has appeared on my iphone. Unless this time there is more than dust, I notice a piece of white string along the edge of the screen, like some sort of hair? Sure it is inside the screen, so that no matter how hard I tried, I just couldn't get it off. I am thinking about go to apple store tomorrow to get a replacement. However, rumors indicate that most likely I will get a refurbished one. You might say that the refurbished iphone is the same as new one, but to me, replace my newly bought iphone with an refurbished one is highly unacceptable. I have not even used it! Otherwise, can i return my iphone? Will Apple charge me any 'openbox' fee? (without open it, how do i know it is faulty!) Many Thanks !
