Orginal apple dongle

Got this dongle/cable from apple for sale.

Has a armprocessor inside

This dongle can be used with apple’s serial number reader (kanziSWD) via mac

I assume it has more hidden features, as its a little exaggerated to build such a complex thing to read SN from death boards.

When I was still in GSM-scene I was interested in such tools for reverse engineering them, you seem to learn the most from original tools.
