Default MMS in Norway (Telenor)

I got my Atom from Singapore a couple months ago and have never been able to send MMS messages. I have reviewed the settings several times and matched it againts the manual settings at telenormobil. I can recieve just fine, but when I try to send it stops at 99% and gives me an error messages telling me that not all messages could be sent.

My Atom has the ROM version from the 26th of April.

Any ideas or suggestions?
