Troubleshooting

In the event the CryptoPhone shows unexpected behaviour, device
response becomes very slow, or it does not connect to a GSM network,
you can quickly reset it by pushing the stylus into the reset hole on the
left underside of the device. The GSMK CryptoPhone will restart without
erasing the memory.

(Cold Boot •25•) 

In the unlikely event such a problem persists, you can

Cold Boot the device (see page 14). This will however erase all information
in volatile memory.

Security Updates

In the event anyone discovers a flaw in the CryptoPhone, we will provide
a firmware update, as well as a detailed and honest report on the possible
security impact. As bad as security problems with cryptographic products
can be, we believe the only way to handle them properly is open and
transparent communication with our customers. You are the one best
suited to determine potential damage to your interests, so we will provide
you with all the known facts. Security is not a state but a process. And
this process requires constant checking against emerging risks and new
attack methods. Since the CryptoPhone comes with full published source
code, the chances are much higher for a flaw to be discovered and fixed
quickly than with any closed-source cryptographic product. Our advisory
board of distinguished cryptographers and security researchers aids us
in identifying and countering potential threats based on their intimate
