I want to sell my sony ericsson aino which I have been using for last 6 months. I got a quote of £53 from FoneHub on this site, but before dispatching my mobile, I would like to confirm one thing. I got Sony ericsson MW600 bluetooth stereo headset with the mobile, so do I need to send the bluetooth headset too with the mobile to them. If not, if I keep it will it be compatible with Arc, which I am planning to buy. Thanks in advance :)
