Would you recommend a specific one?

What should I do to enable it? At the moment it is not showing in rfkill
list, even while I monitor the lack of satellites fix with:

echo 'AT^WPDGP' > /dev/ttyUSB0

cat /dev/ttyUSB3|grep GPGSV|grep -v 00

*$ rfkill list

0: phy0: Wireless LAN

        Soft blocked: no

        Hard blocked: no

1: hci0: Bluetooth

        Soft blocked: no

        Hard blocked: no

I read http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module
which mentions /sys/devices/platform/thinkpad_acpi/rfkill/rfkill0/state,
but I believe it depends on the ACPI entries to show up.
