On its back, two strips of soft-touch plastic break the back into segments: a removablebit up top that houses the 3.5mm headphone jack, a micro-SIM, a vacant microSD slot (the phone comes with 16GB of internal storage) and a fixed piece at the bottom, above which you'll find the Xperia logo.
The Note 8.0's back is non-removable, but that bit's rendered moot by the accessibility of the microSD and micro-SIM slots on the tablet's left edge and a sealed 4, 600mAh battery.
Of course, there is still quite a bit of work to be done to make this work: iPhones do not have removable batteries, nor do they support multi-tasking, meaning that some sort of ruggedized, battery-powered external case would be necessary to get this battle-ready -- as well some jailbreaking.
