Any Splicing Advice?

I'm trying to create an adapter for the BB8130. Just as a point of reference, the Seidio product ADA3-BB8100M35FST is exactly the OPPOSITE of what I need. I'm looking for a 3.5mm male on one end to plug into the BB; and a 2.5mm female on the other end, into which I will plug the lead from my helmet (it has its own connect/disconnect controls). I'm trying to hear music and make calls. So a 4-conductor jack/plug is necessary.

Seidio/Radio Shack/eBay/etc. (I've searched) do not have the exact fittings (and the other seidio adapter http://www.seidioonline.com/index.as...ROD&ProdID=808 does not work for the newer models or for music AND calls, but I'm not sure why). And other posters here say that the iPhone adapters don't work on BB.

I'm not capable of building from scratch (I read davidmkelly's guide to pin outs, in this forum), so I am thinking about taking the full-function headset that came with the BB (because that was designed for music and calls) and snipping the cord just before the connect/disconnect button, and then splicing on a 4-conductor female plug.

Does anyone know if this will work? Any tips or tricks or other ideas?

Interesting, not 100% sure could trial and error and see if it will. I'm certain there is a way to make this happen

Google for iphone headset adapter. There are some that have a 3.5mm that plugs into the phone and the 2.5mm female that you plug a regular cell phone headset in.

This is one:
2.5 mm Adapter: 3.5mm Stereo to 2.5 mm Monaural Audio (http://www.1800mobiles.com/2-5mm-3-5mm-adapter.html)

Works for the Curve, but I thought the 8100 series has 2.5mm jacks.
