Because this teardown is a 3G model that is upgradeable to 4G It obviously has the blank mini-PCI interconnect board and all the pin connections. If (hopefully) Motorola releases a WiFi only XOOM in the U.S. and they leave all of the pin connections in the device, would it be possible to do a 4G upgrade to your WiFi-only XOOM? Or will it not have any of the chips needed to take use of the LTE radio?
