I got this to work and it's great to finally have this. One thing I wanted to point out is that when I first installed this using the .cab method I got the same problem a couple of other people mentioned with the screen looking more like a normal email screen and it had
user@user.com as the from address and showed the picture I wanted to send as an attachment like a normal email. I uninstalled the software, went to Start->Settings->System->Memory and closed all applications there and then reinstalled and it seemed to work fine. I'm not sure if maybe closing the apps helped or not but just wanted to throw that out there in case it might help someone else. Thanks again for all the help! This is awesome. I'll be anxious to hear if you get the video sending over mms working. If I can be of any help with my sprint 700wx please let me know.
