Used the attached CAB and the following UC script to make it all happen for you:
<wap-provisioningdoc>
<characteristic type="Registry">
<characteristic type="HKLM\Software\MobilityDojo.net\DojoSig">
<parm name="Signature" datatype="string" value="{put your sig here}" />
<parm name="UseReplyForward" datatype="integer" value="1" />
<parm name="UseSignature" datatype="integer" value="1" />
</characteristic>
</characteristic>
