CM10.2 or Cm.1 and Sprints 800SMR

[derface19]

Ok. I know few spots are have Sprints 800SMR live and even less have a chance of running a CM10.1/.2 Rom. But On stock 4.1.2 or stock-based rom. I connect to 800 on que and i'm on sprints 800 network most of the day as it is coming out of testing stages. But with Cm10.1/.2, I never connect to the 800SMR. I don't know why either. In home I need to connect to 800 or I roam and loose calls. Any ideas?
