One silly question... typical IT reply, but it wasn't asked: Have you uninstalled/reinstalled fMMS? Maybe something else you did clobbered the settings in some way? Can't hurt to try... Also, if you're getting MMS notices (pushes) but can't download, that sounds more like a settings issue. It could be your provider changed the name/IP of the MMS gateway. Most devices with full MMS support can get those changes via a push to the device (often via a sim push/update). The N900 lacks both native MMS support and sim tools. Check their web site and make sure your MMS gateway settings are correct still. (And if they're not please update the wiki and reply here once you've fixed it. ) Edit: One other thought, If you have a separate advertiser (like knuthf mentioned) it may be the MMS settings for that service are different than the one for your main provider. That would suck, but would explain if you can get some MMS but not all of them.
