SHARP GX10, MMS, kannel

Hello list,

Was anybody able to receive MMS though kannel using Sharp GX10?
I can not find what this phone is expecting from gateway.
I see that on MMS sending it communicates with gw the same way as nokia or
sonyericsson.
My mmsc receives the mms correctly  and forward it to destination without
problem.
Destination ericsson T68i without any problem shows the mms, but gx10
reports server error 
and thinks that mms was not sent.
On mms receiving gx10 sends ACK on m-retrieve-conf and then immediately
drops the wsp session.
On screen it reports server error again.

I suspect that I have faulty copy of GX10, but I'd like somebody to confirm
it
