doesn't sound like the mogul's fault to me, especially since it worked when you were roaming. I've had rare problems like that every once in a while, but have had those with all phones including non-pda phones, but never to the extent you mention, including with the mogul. If everything else is working fine and I imagine it is, and especially since it worked when you were roaming, I'm putting my money on a sprint network messup.

On another note did you flash back to the standard radio or are you still running a beta radio? Are you running the most recent official rom? Have you checked to make sure your MDN is the same as your phone number in ##778#? I had my temporary sprint number in there for a while and it caused weird problems for a bit (as that is what they had me program in when I activated my phone)....
