Palm has posted an update for the Treo Pro smartphone today. The unlocked Treo Pro Bluetooth patch fixes a bug found in the Treo Pro while using a Bluetooth headset.

"If you are in an active call using bluetooth car kit or bluetooth headset and you receive a second incoming call and you let it ring or you ignore the incoming call, the call will be diverted to Voicemail. The first call remains active but you can no longer hear the caller (the caller can still hear you). The audio has been lost. If you answer the call and swap between calls or reject the call, the issue is not seen."

You can get the update at the link below.
