Awful Bluetooth

[sndtubes]

Has anyone experienced terrible bluetooth performance from this phone? Mine will disconnect while talking and often will say it's "connected" where it is not connected. I can make a call and talk for a half an hour with no problem and then hang up and try to make another call and the stupid thing won't connect again. I'm on my second Epic (not for this issue) and they both behaved exactly the same. It may be my bluetooth device which is now pretty old (Plantronics 590A/E). Are you guys finding the bluetooth to be stable or not?
