When I first bought the DX, my Comcast e-mail would always automaticly appear on my phone. Recenty I've noticed that some of my e-mails aren't being "pushed". I have to manually go into the e-mail app and refresh the program. I've tried turning the phone on/off and taking the battery out but it some times still won't "push" e-mail's like it should. All my e-mail settings are correct. Any idea's??? Anyone ever have this problem?
