In my relentless pursuit for not using mobiles while driving, I realized that I have an extra cell phone, since I changed carriers. It worked (Bluetooth) very well in my Acura and there's nothing wrong with this mobile, except I haven't used it for a couple of years. Still in very good condition. See Sony Ericsson T608, http://www.phonescoop.com/phones/phone.php?p=228
for description and technical details. Original cost was over $200. Would this phone have any value nowadays? (I know about Craigslist).
