Among the things they have revealed is the front panel is now fused with adhesive, requiring some heat to remove. Luckily for the LCD, it is merely secured by couple of screws. The battery is said to be 6930mAh at 3.7V. During the dismantling process, iFixit used a standard Philips screwdriver and they didn’t encounter any weird looking screws.
On the smart cover, iFixit has showed that the easy snap on action is actually made possible by having a strip of magnets lined along the side opposite the volume controls. The sleep/wake action of the smart cover is sensed by a small circuitry which detects the magnetic portion of the cover.
Check out the step by step dismantling process after the break.
