3rd Party iPad 2/New iPad cases
Apparently the magnets were placed in different parts on he new iPad. The Apple Smart Cover Case will work because it has enough magnets to cover old and new positions. 3rd Party covers for iPad 2 that are claiming to be compatible may not be, at least for this feature. I have tested 3 existing cases for iPad 2 that I own, they all fit ok, but the Smart Cover feature, does not work....
