[RFI] UDH in MO messages

Can anyone send me a UCP example string of a long text message and a picture message so
I can see if my smsc is broken or if we're gonna have a problem with MO udh interpretation...

This is the first part of a picture message:
<19/00389/O/52/mylargeaccount/mymobile////////////0000/080302153641///
/4/1120/0B0504158A00000003010301300000014202010000481C01000000800
0000000000000000400001000000038100004400010000044000400A10C00000
042010A11128200000049C25129544100000030221544A54120000001010A544
28200100200008428A10102000000004A10A28084400002088A28A2800400020
0C10A28A28008000041010A28A28030///1/1//////0201F50D0100///2E>

As you can see, UDH is embebed in text message and I don't find any bit in 
ucp specification like UDHI in PDU.

How could we know that there is a udh in there ?
Is my smsc broken ?


Even stranger is when I send a long text message through my ericsson, I receive this:

<26/00106/O/52/mylargeaccount/mymobile////////////0000/080302165103////3//60///0///////0201000D0100///0D>
<27/00106/O/52/mylargeaccount/mymobile////////////0000/080302165105////3//60///0///////0201000D0100///10>

Two almost empty messages (I haven't sent any grave accent, but several "monomoo monomoo ...")

The same message arrives ok in a nokia (two messages with message 1 of 2  and 2/2).

Any ideas ?
