I bought a new 8gb iphone from the apple store in cambridge side a couple of days ago, noticed that the screen had a negative black effect, and wanted a week 38 screen with the better lcd version. found one, and we switched them out of at the genius bar. the 8gb iphone i have now is refurbished though (model says FA712). this might have even been a refurbished model that was actually new, but I feel like I should get $50 back (since it was still within the 14 day frame) putting me at the $350 8gb refurb price. what is the best way to go about this would you think? if i cant get it, not much of a big deal. but i feel like apple owes me that.
