Just got my Mogul on Friday 8/31. Did the manual install instructs listed on page 1 of this thread. From there, I wasn't really sure what to do, but I then figured out I was to use the "MMS pix" account when sending pic mail. Now that I know that, it works like a champ.
I can't get video to work, but I think that is simply becasue I haven't made a video less than 350K yet to do any testing.
One thing I can say after reading this 15 page thread...DO SOME READING PEOPLE!!! Your phone isn't just a phone, it is a COMPUTER!! If you don't know how to program a computer, then do NOT expect to just pop stuff into a smart phone and expect Houdini like tricks to come out of it!! Which is usually then followed up by n00bs just freaking out and not even doing a basic RTFM or FAQ check.
Sorry, but its just cumbersome to pick through these 15 pages of rants over 5 simple lines of instructions.
