The Phone Book Access Profile of Bluetooth is much improved in PR1.1. I have Nissan Connect in my car, and previously I could only see a list of phone numbers when I downloaded the phone book, but now I see 'Last Name, First Name' reliably for everyone.
This is even better than the N900 with newer bluez libraries copied over, which I was using before. That randomly stored some people as 'First Name Last Name'.
