Disconnect the headphone and click wheel cable from the logic board. It's tricky to see what you're doing, so you'll have to feel the connector inside the iPod with the spudger.

You need to pry the connector toward the front of the iPod until it comes loose from the logic board.

Do not entirely remove the headphone jack. The cable is still connected to the click wheel.

Use a spudger to push the logic board assembly out of the casing. The click wheel and headphone jack should remain in the iPod.

Be careful not to catch the headphone jack and click wheel on the logic board as you remove the logic board and display.

Completely remove the display and logic board from the iPod.

We got it apart!

The casing is certainly more scratch-resistant than the previous Nano. We were careful and didn't scratch the case at all.

Pry the metal bracket off the back of the display. Make sure you only pry off the bracket and not the clear shielding on the rear of the display.

Lift up the display and use a spudger to flip up the black plastic retaining bar holding the display ribbon cable in place.

Slide the display ribbon out of its connector and lift the display off of the logic board.

Right: old Nano logic board and battery.

The new battery is thinner, but significantly larger.

The new Nano uses Samsung flash memory, just like the previous model.

Whatever you do, don't throw your new iPod into a fire!
