iPhone 4, iOS4: iPhone Stuck In Headphone Mode Even When No Headphones Present

Today I got some condensation on my iPhone 4 and immediately afterwards it appeared that the phone was not working properly. Finally I figured out that the issue was simply that the phone thought that headphones were plugged into it when in fact there were no headphones plugged in. This caused numerous issues including the touch screen sounds to not be heard, me to not hear when people called me though they could hear me, the iPod to not play through the speakers, and any other sounds that you would hear directly through the iPhone speakers. After tooling around with the headphone jack I was able to get this working properly again as explained below.

The first one that I created, using the method we documented in this previous article, is the sound of a dial-up modem connection.

After troubleshooting I finally figured out a solution which is documented below.
