yes vodafone had removed picture messaging when i upgraded to my new n900 in January, however i called them yesterday and they told me this service would be available immediately.
I called them back to confirm picture messaging had been added and they confirmed it had.
now this was strange. I tried rebooting the phone. After that I could delete sent messages, but not recieved (in Inbox).
Then I was going to try deleting from message, but those messages (that I tried to delete) I wasn't able to open.
It seams that the messages are deleted, but not in the Inbox.
frals, You're a genius! It fixed my problem was with the size of the image (240x180). Now I can see pictures in the full size !
Before I'd used this command, I checked the file "%gconf.xml" in the /var/lib/gconf/apps/fmms. And I saw a useragent is "NokiaN95...." I tried to change this to N97, but nothing happens, and after this I used your command and now I see pictures in the full size !!!
they weren't especially helpful or friendly... as far as they are concerned it's not their problem and I should test my sim in a different phone... great!
