Exchange ipad 3 for iPad 4
Ok, as promised this is my update on this, today I took my 2 iPad 3's back to the Apple store, as stated previously one was bought 30th Sept and one on 6th Oct.
The store honoured what they said completely so 10/10 Apple again for brilliant customer service. They gave me a full refund and I then purchased a new ipad 4 and my wife decided she wanted a mini which we bought instead of the other ipad 4.
The store was Garden City in Perth, I restored using iCloud and everything was up and running within 30 minutes, so easy.
I have a laptop which runs windows gathering dust, I hate windows it's so slow to start and always has a problem of one kind or another, if I was able to run a mac at work I would.
Good luck to everyone trying to exchange, it can be done.
