I took ipad air to a 'genius' yesterday and asked if there was a known problem with ipad crashing. Was told I was the first that they had come across! They did a DFU and said that would fix it but if it didn't it would be replaced.
I suspect neither options will fix it if it is in the iOS.
However they insisted that I SHOULD NOT BACKUP FROM MY ITUNES BACKUP as it would reintroduce the problem, this sounds illogical to me unless they have a different iOS to restore to my machine.
As I have a heap of stuff on the backup (many years of ipad stuff) I would like to restore that backup.
QUESTION: is the in-store DFU the same as I can do myself? If so I might as well recover my backup and if it is intolerable do my own DFU after I take action to save all my data? Hope that makes sense.
Ps I pleaded with genius to say there is a problem, don't waste your time coming here until the fix arrives but no, I was the first person with the problem and the "usual" 'I don't read discussion boards'.
