They all match up as well. Just put it on and registered it using her apple id and password and was hoping it wouldn't notify her iphone but it did, i told her she was getting the original ipad air but apple emailed her to say that someone has accessed her account and in that email it says it's a ipad air 2
Good shout about the charger, I bet that's what has happened, not sure if Amazon will swap the charger without me returning the whole I pad but will give them a ring tomorrow. Unfortunately no Apple store around here so can't change it there.
Weirdly when I connected it to the wifi the signal went down on the router ,turned it off and it was sound again, turned it back on and the same happened but it eventually kicked out of it and all was fine again. Bit weird.
