Wireless Data

My Motorola 710 is out of service (my wife placed it in the washing machine with my golf shorts!). Verizon wants to replace it with a refurbished 710. I was thinking on the newer Motorola E815. The best Bluetooth feature on the Moto 710 is that I got it to work as a Modem on my Mac Powerbook G4 laptop. Will the Moto E815 work as Bluetooth modem also? It seems from my research that the E815 only works with Bluetooth headsets. If this is true-can I hack the phone to sync up Bluetooth via my laptop?

Also, does anyone know if the E815 can also sync with with my Mac Address book? The Moto 710 does this and it's a great feature. Thanks for your help!
