Others have probably figured this one out, but from my searches I found no other posts.
I am somewhat of an audiophile, and i wished to use the in-ear headphones which came with my Sony Ericsson Walkman W810i (old phone) to listen to music on my universal. unfortunately, these earphones have a 15cm cord, which won't even reach into my front pocket. To fix this issue, I decided to get a handsfree adaptor (why pay ~$5 for a plain old extension cord?). Mine cost ~4.50 AUD on ebay from hong kong, and was originally designed for an iPhone. Many people have assumed that these (plain 1 button + mic + headphones/headphone socket) iPhone headsets will work with the Universal. this is not the case. After pluggin this in with my wonderful sony heaphones I noticed taht the sound was tinny and sounded very washed out. I realised that this was because the ground pin and microphone pin on the universal are in opposite locations to those on the iPhone. The ground wire (feeding the power back from the headphones to the Universal) was going through the microphone first, and it's semi-conducting nature was screwing up the sound. Holding in the button (completely analog, just provides a fully conductive bridge on the mic channel) fixed the problem. So to fix this whole issue, I opened up the case of the headset adaptor (where the mic is) and swapped the wire from the headphone socket ground to the other side of the switch (which connects to the other wire (iPhone mic/Universal ground)) with my soldering iron. It took me only about 5 seconds of soldering and it was done. After snapping the case shut again, the headphones now provide excelent quality for my hardstyle beats:D.
I do have a question still though. On the iPhone (and Universal) the mic pin is grounded to provide a button click. This pauses and plays the music and answers phone calls on the iPhone, and a double click skips to the next song. Does this button answer phone calls on the Universal (I don't have a Universal headset and never have. I think it has a button, but correct me if I'm wrong). Is there any software/driver I can install to let this button pause/play and/or skip tracks in media player/pocket player? This would be very usefull software, and should be easy enough to write if anybody has the skill/desire to make this software (since the microphone is accessible to software, isn't it?). The signal should change from the mic having lots of resistance to having effectively none (showing a constantly high signal for microphone (not wave)). Maybe it could just be programed to run as a hardware button so that other software (such as voice command) can use it.
I'm unsure if this software exists already but I havn't found anything in searches:(.
Thanks for any help you can give regarding this software, and also happy modding to anybody looking to convert an iPhone headset, I hope this info helps.

If the phone uses the headset button as the "green button" then maybe this software is still possible. Call Of Duty 2 for pocket pc uses the green and red buttons as game controlls, which doesn't change to the phone applications.
