Need to know differences between iPad 3 and 4 PCB(interconnection)

Does anyone know differences between iPad 3 and 4 PCB(interconnection) board? I am looking around and have only been able to find the interconnection board for the iPad 3 wifi, I need an interconnection board for the iPad 3 Cellular GSM. The only one I have found seems to be dual listed to work in the iPad 4 as well. I have trouble believing that.

On the cellular version one of the antennas plugs into this board.

Answer this question I have this problem too

Is this a good question?

The headphone jack is soldered to this board. The antennas plug into it as well as the power buttons.

It is the sensor panel assembly, it houses the headphone jack, front camera/ALS, mic, gyro/accelerometer, rear camera, front end modules for one of the antenna, buttons and compass sensor. A lot of ipad3/4 parts are interchangeable, this could be one of them. I don't have the schematics for iPad 4 so I can't say for sure.

The headphone jack in ipad 3 cellular is not soldered to anything, so I guess that is one difference :)

Hi Jessabethany, after review it does appear that the headphone jack is soldered to the board in question.
