Hi there and thank you so long for your help.
I have had my iPAD 2 with Smart Cover for almost 10 days now and I am loving it.
By default, the iPad Cover Lock/Unlock is switched on. I have noticed that when I want to use my iPAD and fold the cover to the back that it puts my iPAD on sleep. Interestingly enough this does not happen with my brother with exactly the same pad and cover.
Am I doing something wrong?
