PHONE PROBLEMS?

Did something happen to Verizon? Is it possible for cellphone systems to become infected by a virus or something? None of the calls I'm trying to make are going through, and I can't seem to send text messages either. Maybe it's just my phone that's being weird? What's wrong with you, phone?

edit: I got the brainwave to try calling my cellphone from my desk phone here at work; it rang four times and then voicemail picked up. But I had the phone in my hand, and it never actually rang. It appeared completely oblivious. What the hell.
