I've seen plenty of adapters for sale that allows one to use normal stereo earplugs with the TyTN, such as on http://www.doml.net/productdec.asp?p...TN&modeln=TyTN
The pinout seems to be Pinout from Tracy and Matt's blog
Should I, perhaps, just bust open the crappy Cingular headset and do some soldering? Will the impedence for the microphone be the same? How should I combine the stereo that they have in the crappy headset to the mono that all 2.5mm jacks use?
