i got another phone over CL its iPhone 5 32gb. i verified the serial and it has applecare+. the phone is in good condition but there is a scuff and scratches (OCD kicking in) can i just walk to apple store and tell them to replace it? i don't see any fault except for these marks at the back and I'm annoyed by it. i understand that i will pay $49 or $79 not a big deal. I'm just concern walking in and tell them that it has scratches and i want a new one.
