That sure does have something to do with your issue, my guess is you will have to restore your Stock Nandroid rom if you made one, then update your Profile and PRL and then I bet your service will work again
If I were you I would open a new thread up in the all things root section, and you will get more responses, because your phone is rooted.

Not sure if that's a problem, but it didn't sound good.
Either way, I have tried calling Sprint, but they try to walk me to Updates and I don't have that option anymore since I rooted last year to the Froyo software. I'm not comfortable with all of the flashing and should be considered an extreme noob on these matters, but any assistance would be fantastic.
Oh, one more note that may or may not have relevance: My wife took my upgrade to get a new phone right before this issue was noticed. They had to deactivate my phone briefly and then reactivated. Again, not sure if this has bearing or not, but wanted to throw it in there.
