Take off the plastic cover/frame. It's pretty loose after taking out the screws, so it should go off pretty easy. The kickstand is on that frame, too.

The thing you see now is the "inner life" of your phone. Be cautios and don't touch anything else than the microSD slot.

The microSD slot is next to the SIM card slot. The microSD card itself is hidden under a silver foil.

Take the silver foil off the card. It's glued on under the slot, so you don't have to take off the whole foil. Just enough that you can get the microSD card out.
