Thanks for the link. I've applied both CABs now. Unfortunately, it's now worse than before. I'm not sure if that is the result of something done by tech support, or me.

Now when I try to download an MMS message, as far as I can tell, the phone is doing nothing. No indication it's actually trying to download it and no error message. Support had me enter a username (<10 digit>@vzw3g.com) and a password of vzw. However, as far as I can tell this is not saving, because every time I look at this it's blank.

Also, if I try to force a data connection, I still get:
Data Call Failure
Error Code: 4
Network Authentication Failed
