The question is in the title of the post. :)

The Apple website says:

3.5 mm headphone jack

  • Support for Apple iPhone headset with remote and microphone
  • Support for audio line out (digital/analog)

Does this mean that the port is also a line in for the microphone?

Yes, you can use the port as a line in. As detailed in Apple's support article,

  1. Plug the input audio device into the combination audio port using the proper adapter cable.
  2. From the Apple () menu, choose System Preferences.
  3. Choose Sound from the View menu.
  4. Click the Input tab.
  5. Change the "Use audio for:" menu selection from Sound Output to the Sound Input.
  6. The device type should change from "Internal Microphone/Built-in Input" to "Line In/Built-in Input."
