iFixit has performed a teardown of all three iPad 2 models comparing the differences between them.
Apple still managed to infuse something different for each iPad 2 flavor.

But the empty space was magical, per Apple rules, although startlingly devoid of anything.
But not all differences were restricted to the logic boards. There GSM, CDMA, and Wi-Fi units also had different numbers of antennas that handle the WWAN reception for each model. Notice that the CDMA version has one additional antenna connector when compared to the GSM version
