Pondering construction of a secure telephone. (Or at least a cellphone in general. The user interfaces and features available on virtually all the mass-market phones suck, to put it very very mildly, not even mentioning that there's no access to their firmware (so no chance of audit), poor or no support for SSL (while running HTTP through the operator's proxy), and typically no possibility to run more than one Java applet (or other program) at the same time. A combination of a GSM/GPRS module with a suitable embedded Linux-running computer could be the right solution.)
How about building a secure cell phone using GnuRadio as a core? That way you have maximum control afforded by the protocols. steve
