I don't know if anyone is still reading this, but I'm on telus, and I have played with some of the settings in arcsoft. Something I found interesting was that I would get an imediate error when using mms.telusmobility.com/servlets/mms, but then I changed the server info to
http://phone#####:razz:assword@mms.t...do/LegacyLogin, and it seems like it was trying to connect. As it took about 1 to 2 mins. longer to tell me it wasn't able to connect. Maybe you guys could try doing the same thing with your providers.
For you telus users, I just put in
http://phone#####
assword@www.telusmobility.com/snap
and I think my mms was sent
EDIT: Never mind its not working with that either.
