Data connection dead?

[Oxymoron238]

I've tried to search this out before starting a new thread, but I haven't found an answer. All of the other threads discuss problems similar to mine, but they aren't quite the same.

The problem starts when an icon (that looks like the data connection arrows) appears in my taskbar. As long as that icon is up there, I can't connect to the internet, my weather updates won't work, and any other data program is rendered useless. Soft resets don't help, because the icon comes right back when the phone comes back on. I've restored a back up file and cleared it temporarily, but it just comes back a few days later. What's going on?

EDIT: I forgot to mention that I'm on the latest edition of Mighty Rom, if that helps. This rom is AWESOME by the way. This is the only problem I'm having while running it, and the issue may not even be with the rom.
