I bought it at a currys digital shop as there was a queue at the apple store in Cardiff this morning. Will I get more joy going direct to the apple store, or should currys replace it?
Apple will likely not replace it if you didn't buy it direct from them. Take it back to where you bought it. Technically one dead/stuck pixel isn't covered under warranty, but most stores in the US at least have been lenient and made exchanges.
I picked up a 32GB iPad 3G this morning. Got it home and started playing, then noticed a single dead pixel. It is stuck on red.
Anybody know what Apples policy on dead pixels is?
