Nokia 3310 tracing

Hi,

I've put together a small program that puts Nokia 3310 phones into debug mode (via serial/USB cable) and forwards all sent/received GSM messages and SIM APDUs via GSMTAP to be viewed realtime in Wireshark. This allows you to see the message flows for a real phone on a real network.

Nokia 3310's are very cheap and easy to come by, so should appeal to a wide audience.

Thought osmocom might be a good home for this utility - could it go into git, and a short page on bb.osmocom.org?
