have a look at my thread here

the GPS is an autonomous entity inside the modem which can give you position data at "/dev/EG25.NMEA" or you can request it with AT commands
I don't know which distros are already enabled to read the data out of the box
the location fixing is difficult, you have to wait and be in a quite unobstracted space, some people say that it works faster with an external antenna
