Ok so I un-installed fAPN, then made certain my connection was set to O2 MMS & updated to the latest version of fMMS being 1.2.9 & tried to send a MMS the first time I got Network un-reachable & the second time I get this ..

Operation failed
MMSC: 200_OK
Body 00 00
01 04 J

I will now try set up on my wifes N900 & see if there is a difference.
