I rang up the store today and told them about the yellow screen tint and asked if i could return it. The guy said yes and because i am still in my 14 day return policy i can get a brand new boxed one instead of a refurb but because they are still selling really fast i would have to try and order one online the night before at 9pm and if i can't get one i can swap it for a refurb. I tried tonight and got to put one in my basket but as soon as i logged in they went (same happened to my girlfriend as i also got her to try for me) When i rang the store earlier and asked them about the refurb one the guy said that we do have ones that come in a black box behind the genius bar counter that are normally refurbished ones but because the iPhone 4s is still new they have not actually come from a previous customer and been refurbished. I asked hime where they brand new then and he said no he and he didn't know what they were. Do any of you guys know what they are supposed to be? Also when i take it back and received one of the so called refurbished ones, what if the refurb also has a yellow tint? can i ask to look at another and another until i get one with a good screen? Thanks.
