Thanks, added.

Since the (Sony)Ericsson devices use standard drivers like cdc-acm and
cdc-ether, we don't know that they need special handling unless we tag
them explicitly.  It's a good thing they use the standard drivers, so
the tagging bit is a fair compromise.

Mind sending a mail with that information to the usb_modeswitch people?

that'll allow everyone to benefit from this fix.

We don't have GPS support yet for these device yet in MM, but that
should be fairly easy to add if somebody had the time...  The commands
are well-known and ModemManager has good location services API that's
already used for celltower positioning if your modem can do it.  GPS
would be great though.
