It's not "dodgy" - this doesn't effect the performance of the phone in any way, nor does it really effect anything. It's a minor cosmetic issue that has NOTHING to do with how clean your hands are. I wash my hands all the time. My yellow 5c has the dark ring around the sim tray.There is a minimal gap between the phone casing and the sim tray cover, so of course grease and crap is going to collect in there. It is a pure white phone, so anything slightly off white is going to contrast the beautiful finish. It's not a big deal IMO.
You can't really go by the store models anyway. People are nasty and don't wash. I like to keep my hands very clean.

You must have a dodgy phone, because the sim tray on my 5c is completely flush with the casing. If I run my finger down the side, all I feel is the hole for the sim removal tool.
Yeah that's true. My iPad is white but there's no sim tray or anything where it could collect dust/dirt/whatever it is like that.looks fine to me, I think you never had a white piece of tech... spaces get filled w/ all kinds of stuff and white just makes it more noticeable .
