The Naughty Bits
Now that we know the dumb bit on the right is much much heavier than the smart bit on the left, let's find out just how smart that "smart bit" is.
After snipping a few wires, the main board of the phone frees itself from the frame without much trouble. You'll notice that the main board is wired to all sorts of things including the antenna, the flashlight and the USB charging port using some flimsy bits of wire. It's worth mentioning at this point that the flashlight is really just an LED with some heatsink material behind it wired directly to the power rail through a slide switch.
If this is the speaker that the box brags about then the box is half right. It's a 'large speakers' but it is most definitely not a 'streo speakers.' Let's flip it and check out the keypad.
That's definitely a pretty standard keypad, but wait a second... what's this underneath?
What the heck? It's a secret keypad. I told you this was some kind of spy phone. I'm assuming what happened is that the fine folks at DDC Mobile bought a bunch of phone boards and a bunch of rubber keypads but they weren't compatible... so they had to stuff in another board to match them up.
So... there's a sticker. I was really hoping it would hold some clues for me but I don't know how to decipher this at all. This is V2.0 of the board, though, so there must have been one worse. That's progress of a sort.
