I have a new issue w/my curve. At night I shut off my network connection andfor the last 2 days it gets stuck in digital roam, and won't receive emails. Yesterday, a batt pull did the trick, but today it wa a soild hour after the batt pull before it started getting my email. So what do you think is wrong with my curve? Oh I use sprint and I have SEP.
I don't know what is wrong with your phone or your service. But a solution to your problem seems self-evident: don't turn off your network connection at night. If you don't want to be alerted as emails arrive, set your profile to "Phone Only" or "Quiet."
There is nothing more important than my beauty sleep so I just leave everything on and put my BB at the other end of the house and keep my normal settings.
