The "open hardware" phone project that's had the most interest

[Kai Lüke]

Hi,
GTAx is allready more extensible than normal smartphones because of usb
host mode. And any different fast data connector I think about might
allow an attacker to get access to your system, like the hacks with
firewire.
I also think it would be nice to have modular phone, but this is a huge
goal and seems to need serious research and many iterations of practise
before you are happy with it.

Regards,
Kai
