I know what your talking about. In EnergyROM I goto Start //Internet //Send & Receive All //Menu (At the Bottom) //Scroll Down to Pic/Video Options...// From there I get the Arcsoft Setting and goto the Server Tab at the bottom like you mention and the Only one is Cricket MMS. I tap on it, and I get the option to change what you discribe.
Server Name is Cricket MMS
Gatway is nothing/empty
Port is 8080
Server Address is
http://mms.mycricket.com/sevlets/mms
Connect Via is Cricket
Send Limit is set to 1000k
But i notice that at the top the title bar says Outlook E-mail (Next to the Start Button). I suspect Arcsoft may have the same settings menu for other apps. But the Registry under Arcsoft has no mention of Alltel. I have changed everything in the registry that i know to change under Arcsoft. I have double checked for any strings/value for Alltel but nothing. Just Cricket.
Edit: Okay I found other ways to get to the Arcsoft setting menu, so it seems its not a differant menu for differant tasks. I'm not to sure what the deal is. It has to be something with the registry settings. An uneeded string/Value, Something is interfering. I just haven't put my fingure on it. I am willing to mess with the registry under arcsoft. The worst damage I could do would be to have to use your three cabs to start over again.
