Fixed. The guilty App was "Call Blocker Gold." I'm not sure why my phone suddenly didn't like that app but after two hard resets and a lot of calls to myself so I could figure out exactly when the issue began, I narrowed it down to "Call Blocker Gold." Even when the app was "Disabled" it caused problems.

OMJ,

Thanks for taking the time to reply. I'm running a stock Spring ROM. As soon as I figured out the problem, I wanted to post the solution here just in case anybody else runs into the same problem that I had.
