Ok, I'm on Rogers (Canada), on an unlocked v3x. I've gone through and downloaded/installed the websessions file from the downloads section, and followed the guide on howards forums. Now, I try to send a picture and I get "Sending 0%" and it just sits there.
I just went through and changed a bunch of things to other things. eventually it worked. For some reason, naming the web session to Rogers MMS and choosing Rogers MMS as the web session didn't really work... Don't know why, but it didn't. I just changed it to Rogers 1 and poof.
