I did not manage to test many details, but the initial tests work as expected. I am connected to the GSM network, I can get IP address over GPRS, and I tested elementary Bluetooth functionality (scanning devices around) which showed my notebook bluetooth connection. Connection I made was with FTDI module over 5V rail. Only hooked up 5V, Tx, Rx, GND. Module did not respond initially until I have inserted SIM card. Then it just worked.
