Apple are issuing refurbs as replacements from Apple Stores, brown box replacements, an Apple CS rep confirmed this over the phone.
My ipad 4 was 3 days old returned it to Apple Store to be given brown box replacement, NOT a sealed new White box.
Took me 4 ipads to get one I could live with had yellow scren tint, and the blue haze around the edges.
I shouldn't have had to pay £488 for something I could "live with".
Unhappy with quality control to be honest.
Thinking about it, its 12 days since I paid £488 for my new Ipad and I'm not 100% happy.
Will contact Customer Support.
