Apple’s online store now lists the iPad Smart Case and iPad Smart Cover as discontinued for the iPad 2 and iPad (3rd/4th-Gen). The site now only shows a dark gray Smart Case and Cover, but both are unavailable for purchase online.
Limited inventory may be available in some retail stores.
This is a somewhat curious move, considering Apple has kept the iPad 2 in its lineup.
However, Apple is still selling a number of third-party cases that are compatible with the iPad 2, as well as new iPad Air and iPad mini Smart Cases and Smart Covers.
Update: Apple is now selling dark gray versions of the iPad Smart Case and Smart Cover in its online store again.
