No, not yet.

Yes, here is an example. This is the response from the phone

  42 11 00 00 6A 57 9F B6 41 29 B1 B0 10 8D 84 00 6C 9C 9C 01 B1 0C

This is decoded PDU (asn1c was used):

  PDU ::= {
    referenceNumber: 2
    component: MsrPosition-Rsp ::= {
        locationInfo: LocationInfo ::= {
            refFrame: 0
            gpsTOW: 6969247
            fixType: 1
            posEstimate: 90 4A 6C 6C 04 23 61 00 1B 27 27 00 6C 43
        }
    }
  }

And those are the coordinates from "posEstimate" (I did not care about
the height):

  52.329040 - 52 19'44" N
   5.819342 -  5 49' 9" E

Best regards,
  Dieter
