So I bought an iPhone 6 Plus, but after a couple of days had to have it replaced in my local Apple Store in UK due to a problem with some dead pixels.
All good and well, but as a developer I've just tried to install iOS8.1, and it won't accept the update.
I just looked in the Settings --> General --> About screen on the phone, and I have a model number of NGAH2ZD/A ???
The back of the phone has A1524 etched on it.
As it was purchased in the UK surely it should be the standard GSM model A1522 ?

Has my Apple Store unknowingly given me some odd model as a replacement by mistake?
