That looks simple, but it doesn't show the surface mount chip (or chips) on the other side of the board!.

I didn't realise it was so crude, it sounds like you have to take your phone to pieces and solder wires across it's keypad!.

well... yes! its a bit crude, but it only needs to solder to some number of the keypad! to make a speed-dial... soldering two wires to some cheap spare cellphone is easy!
