That should be the Option 225, which has GPS functionality, but you may
need to enable it with AT_OIFC=3,1,1,2.  Then replug the device, and
you'll get 5 ttys: ttyHS0 - ttyHS4.  To test, send AT_OGPS=2 on ttyHS1,
and then watch ttyHS2 for spew.

If you want to unlock it:

I've successfully used that guy's unlock for my HP Veer so his stuff is
pretty solid.
