I've definitely been thinking about selling it (I've now replaced it two times over) but I'm not sure how much it's worth. I also suspect there might be a problem with the speaker phone mic (people usually had a hard time hearing/understanding me - but it could have been my continuously poor reception).
Sounds like you're interested in buying it. Since I think there may be a problem with the mic I would be willing to give you a week or so to test it out.
I'll have to wipe it before shipping it, and the first chance I'll be able to do that is Tuesday.
