How does the iPhone replacement program work nowadays? Do they open a brand new iPhone box? Seeing that it's only been a little while since the iPhone 6 is released... I remember getting a replacement for my iPhone 4 a while back... and it came from a dodgy brown box...and the quality just wasnt the same.... the screen wasnt as good as the original and it just didnt 'feel' as solid. Anyone had their iPhone 6 exchanged that can chime in?
