Many customers bought a new iPad last weekend, and some found that Apple’s Smart Cover doesn’t work with certain previously Smart Cover-compatible cases. Mark of Mark’s Hangout has discovered why, and he’s posted a detailed explanation.

It appears that Apple added a polarity-sensitive sensor to the new iPad, and that early Smart Covers were made with magnets facing in either direction. Later model Smart Covers don’t exhibit this behavior. We can only assume Apple made an adjustment when it refreshed the line in October.

Mark had help from an independent case manufacturer in sussing out the problem. You’ll find all of the details here.
