Hi, I've literally just opened my new iPhone 6 Plus 10 minutes ago and instantly noticed a really dark blotch in the top right-hand corner near the battery indicator. I'm pissed off because I now have to travel some distance and pay for parking (and petrol) to visit an Apple Store. If they agree to replace it, will it be a BRAND NEW device? (sealed), or will it be a shoddy refurb? if it's the latter, I won't even bother wasting my time. I'm from the UK by the way. Thanks in advance.
