Badly!
The 'hidden sector' count should be the offset from the beginning of the
disk - ie 35.
The filesystem size of 121790 doesn't match the 121821 reported for the
media size (which is incorrectly used as the size of the mbr partition).
121790+35 = 121825, so the fs ends beyond the end of the media.

You want to raise a bug report on the phone...
But that will probably be about as sucessful as we were with some CF cards
that gave incorrect responses to the 'identify' command (or locked solid
when asked to do it.)

Additional sanity checks....

You might find that the instructions with mbrlabel might let you
mount the card.
