True the Bladox product doesn't provide the full source code. But the nice thing is that the creator seems allow for easy hooks and API mechanisms to do do simple MITM things. The issue I have with the Bladox product is that you others enhance the capabilities of the firmware. Even if you wanted to the Atmel chip used has some pretty decent security mechanisms.

Regardless, I think that the SIMtrace hardware is going to be a great addition to the space, and I'm looking forward to it.

The Rebel SIM card (the device which goes between the SIM card holder
and the SIM card) can do MITM. However one has to write its own firmware
for the microcontroller and the hardware is limited (e.g. there is no
interface to a PC).

Another device is from Bladox, the hardware is quite nice however the full
source code of the firmware is not available.

Best regards,
