PhoneLabs' new desk phone, which sells for $249, is a two-line model that can hook up to any combination of land lines and cell phones. If you link it to a cell phone - either via a wire or Bluetooth - it can absorb the cell phone's phone book, so you don't have to keep turning to the cell phone to remember people's numbers. You can check out your cell phone's call log and redial list on the Unity, too. It can send and receive SMS messages and can even do push-to-talk through your cell phone, by hitting the "Call Waiting" button.

The Unity is available now.
