Motorola's XOOM tablet has suffered the screwless indignities of the teardown, with iFixit taking the 10.1-inch Honeycomb slate apart for the unblinking gaze of the camera. The freshly rooted tablet is unsurprisingly straightforward to open - considering that's something Motorola will be doing a lot of, while replacing the 3G modem with a 4G version later in the year - and reveals what iFixit describes as a blank "mini-PCI interconnect board" which seems to be a placeholder for the 4G modem. Interestingly, the XOOM uses the same Qualcomm MDM6600 3G radio as Verizon's iPhone 4, which as you may remember is potentially world-phone capable (the radio, that is, not the iPhone 4). That could imply that the HSPA+ capable chipset won't be changed out for the GSM versions of the XOOM, merely have its GSM capabilities unlocked through software/firmware. In the end, iFixit have glowing things to say about the XOOM's repairability, though they do warn that there are a lot of screws to get past in order to access all of the different components.
