Default [Q] CM 7.2.0 / 9.0.0 Problem

Hey,

After installing CM 7.2.0 or the New one that's come out for the Milestone CM9
I lose Service to Telus. Did anybody else have this problem? What's the work around?
I want my phone to look pretty, Do nice things, and work to top it all off. D:

-Thanks guys!
