Here is an ArcSoft I put together that does a few stuff.... 1.Remove ArcSoft & Picturemail, 2.Installs ArcSoft, 3.Sets up registry stuff and 4.Adds X-MDN with your actual phone #....

Please try it and let me know if it works out. I have the same one but configured for Boost Mobile and it works fine for me. Haven't tried the Sprint version.
