Are the rear housings/ back cover interchangeable on iPad 2 GSM and iPad 4 GSM? Image of it below…. Thanks, Danny

I am answering my own question just in case someone else needs to know FYI . No they are not as the logic boards are different and they mount with screws in different locations and are not interchangeable. The mounting area for volume, mute and power switch ribbon cable is different as well.

They are not. Both have different cables/ mainboards/ etc
