So what is inside the mysterious metal box?
Samsung K9F4008W0A-TCB0 512x8 Kb (512 KB) flash memory (designed for digital audio recording)
Crystal oscillator, covered in the same unusual substance found on the main board.
Unknown IC D16529CAC11CQC. Googling it turns up nothing that makes any sense.
This board is probably where the messages are stored.
