The OLC will reject a Cambridge file that does not have the G-Record.
It has rejected my file that was recorded by SeeYou Mobile in my Ipaq.
Yet a friend has no problem with getting it to accept a file that he
records in his SN-10.

I believe the SN-10 file has no security. Does anyone know why the OLC
will accept this unsecure file, but will reject other non-secure files?
