Sirf Iii Bluetooth Gps Receiver Is It Possible To Have 2 Devices Connected To One GPS Mouse?

Is it possible to have 2 devices connected to one GPS mouse? - sirf iii bluetooth gps receiver

I ordered a Holux GPSlim236 Bluetooth GPS SiRF Star III. I want to connect to the phone from a Nokia N80 and Palm Zire 72 in connection. Both will be used for navigation.
Can I simultaneously two? Or if not, it's easy to switch between them? Do I have any time left?
