IPhone stuck in Headset mode

Question

Id like to report a bug. The iPhone will still think the head set is plugged in (internal ear piece/mic does not function) when I do the following:
1. Use the phone with the head set
2. let the phone lock itself after not using it
3. remove the head set AFTER the phone has locked
Solution:
Right now the solution is to unlock the phone, reconnect the headset and then unplug it. You can confirm if it is working because the "lock/unlock" sound will come through the phone speakers instead of the headset.
I have had this issue intermittently throughout my ownership of the iphone.
Apple PLEASE make sure the phone knows when the headset is disconnected. This has interrupted MANY of my phone calls for both business and pleasure.
Anyone else having this issue?

Answer 1

iPhone locked in headset only mode
Cause: removing a headset while phone playing and locked.
Major symptom: no sound from earhole speaker.
Solution: (fastest) play a song from iPod or any lengthy duration audio clip and allow phone to completely lock. Insert iPhone compatible headset jack. Unlock phone. Stop audio. Unplug jack.
Resetting does not work.
Often I have my phone plugged into some speakers at work through an adapter. I grab my phone to run to lunch and forget to unlock first. Now its useless as a phone.
Workaround until you can get back to a headset: speakerphone will still work, but you will not be able to hear other things (youtube, iPod, etc)
Other way to diagnose problem: when you change the volume on iPod or video clip using the buttons on the side of the phone (not the screen slider bar) the dialog box will say headset.
At first I thought I broke the phone by pushing the jack in too hard, and was relieved to find out it was a fairly simple glitch. I don't think it is going to be easy for apple to fix though. It is pretty annoying.
