Staples has the Samsung WEP490 Bluetooth headset on clearance sale for $4.90. The nice thing about this headset is that it comes with a charger that works with our phone (Same voltage, amperage, and microusb connector), and seems to be much better made than the charger that come with the phone. The other benifit with using a BT headset is that it eliminates the echo issues assocaited with using GrooveIP. I used one on a 25 minute call yesterday, and the results were just as good as a normal cell call. Staples is sold out online, but you can check local availability.
