Wireless Data

I got a Palm PDA for Christmas which is a tremendous help in my work. One of the features is Bluetooth connectivity, which allows me to dial from my contacts in the PDA directly through the (compatible)phone via Bluetooth. As my cell phone is a Samsung and not supported by Palm for Bluetooth connection, I purchased a Moto V197 off Ebay and switched the SIM cards. Now the phone works great with the PDA, but I discovered I can only connect to 1 Bluetooth device at a time. I'd like to be able to connect to my PDA and the earpiece at the same time. What phones (or Bluetooth version) will work this way - if any?
Thanks.
