Hey guys, thanx for the advice, it was much appreciated. However, I did use the correct CDA for my phone and after further research it appears that my operator has put some extra "customisations" on the phone. I think they are stored in the GDFS?? And the problem could also be USIM related.

Does anyone have any knowledge about either customising the GDFS to allow delivery reports or have information on how to edit a USIM?
