I need a replacement headphone adapter.

This looks rather pathetic since I'm replying myself. But since nobody reply to my request, I'll save every one the trouble, and let who ever is reading this know that I've found my replacement adapter. Mobiman adapter worked like a charm. It does exactly the same things that LG OEM adapter does. It works as an antenna, hands free device, and 3.5mm adapter. Thank god I found a replacement, because LG accessories sales department was no help. What you don't see on their web site means they don't have it, so don't even bother to call them to think they may just forget to list the item on their web site. I just don't understand why LG don't make the adapter as a for sale accessory. I mean you can get everything else like the data cable and the travel charger. Also, for those of you that are looking for TV/AV out cable for the expo, I remember this from the Samsung Mythic forum, http://www.meritline.com/hybrid-usb-dongle-tv-stick-geniatech-u6012---p-35677.aspx
The cable uses the mini USB connector, but it doesn't mean that it'll work with Expo. At least it's worth a try. It's much easier than those of you that are taking the adapter apart and soldering the wires.

Okay, so I said that will buy it and got it today. By golly it does work after what "one year". So I hooked it up to a mini rechargable speaker of course a loud one, man, sweet tones coming from it. I'm not srcewing this one up at all.

You had to excuse me, I didn't read your posting carefully the first time. Obviously you're talking about the 3.5mm adapter. I'm happy that I can share my finding with other people in need of the replacement. It was so frustrating to not be able to use the earphones with the phone, and can't by the OEM replacement from the manufacture. I know that if I have to wait a year before I can get a replacement, I'll go crazy. Since the adapter is inexpensive, I went ahead and got an extra one. Now I have one for the car and one for the home, lessen the chance that I'll loose it again.
