Has anyone purchased a Cingular Blackjack? If so, how does it work with the Lexus Bluetooth?

 

Only problem I have is you can't double down unless car is in park-

 

I should be getting one at work early next week to try out for a few weeks. My limited use with it prior to release was that the BT battery life was not good at all. Hopefully it will be better with final code improvements from Cingular.

 

Thank you for your reply.
Based on the fact that it comes with two batteries, I have a feeling the battery life will be poor. Does it pair properly? How about the address book transfer?

 

It paired fine, but I didn't try the phone book transfers. Battery life was not good with the phone, but leaving BT on made it unbearable. You need to toggle it on and off if you want to use the phone for any length of time. You'll definitely want a power adapter in the car.

 

FYI The phone comes with 2 batteries.
