Hi guys! I am considering of taking back my 4S, because of spec of dust under the screen and two little scratches on the display under the glass. I am already crossed the 14 days limit and I am wondering - am I gonna recieve a refurb or new one? Is it worth to take it back for lets say- not so big problems (in the other hand screen tint is excellent, no dead pixels ) and get a refurb? What would you advice me?
