My former phone, a Droid X, did not completely pair with my Benz phone system. It would not load my contacts. I lived with it. When I paired my new IPhone4 it loaded all my contacts and the complete system works perfectly. I am VERY impressed with this phone. The Droid X was really good. The IP4 is better now and when IOS 5 comes out with "deep voice integration", it will blow the socks off the Droid family.
