Packaging is virtually identical to the iPod Nano G2 packaging.
Included: Shuffle, color manual, USB 2 dock, and earbuds (plus spare earbud covers).
There are LEDs on top and bottom of the shuffle. You can't see both at once and they both flash the same messages.
The back of the Shuffle says: Model No.:A1204 EMC No.: 2125 5V 1A.
Let's take it apart!
The top and bottom of the shuffle have white plastic caps held on by mild adhesive. Heat the caps with a hair dryer and gently pry them both up. Make sure you don't pry the metal beneath the caps up at the same time.
Remove the shuffle / loop switch and the power switch.
The shuffle / loop switch is actually a metal arm about .5" long that extends along the bottom to a switch on the logic board in the center of the shuffle.
