Earphone controls not working on iOS4?

[Screwtape]

Since I've updated my 3G to iOS4, my earphones with iPhone controls haven't been working. I've tried two different pairs of earphones, including Apple's pair that came with the phone and the iPod doesn't respond at all to the pause/play control. Anyone else experiencing this? Or is there a problem with my earphone jack?

I update my 3GS to iOS4 and I have the same problem with the earphones and my battery drain to fast!

This happened to me as well the other day. I've upgraded from a 3G to a iP4. I think in my case, it was because the jack wasnt in properly. I pulled it in and out again and then closed the ipod app and went back in to fix it.

It might just be a coincidence.
