Now I know what's really wrong; my iPhone thinks headphones are always connected

iPhone 3GS, 4.2.1 JB

my iPhone is convinced that I always have headphones plugged in. I cannot make calls without a headset, and also it does not ring, which annoys me.

Is there anything I can do to try and alleviate this?

Plug the headphones in and remove them maybe?
Clear out any dirt or anything that might be stuck in there.
You dont have any water damage right.
Sometimes people think its ok to talk on their iphone in the rain even if its a light drizzle.
If a few drops of water fall inside the headphone jack hole it might cause damage.

I never talk in the rain...

I've tried inserting and removing headphones more than once.

Have you tried a restore?

 

[GuitarG20]

yes. I've tried just about everything I can think of... and it's not under warranty anymore either.

 

[Applejuiced]

Sounds like a hardware issue.

 

[heisenberg123]

agreed with applejuice, sounds like water damage or hardware

 

[GuitarG20]

water's never gotten even near my phone though... ><

My iPhone (original) did this a couple of times.

To resolve it I used a cotton bug and some cleaning alcohol and cleaned the inside of the headphone port. It took a few goes before it had been cleaned enough to start working again.

Your mileage may vary.
