Query: Razr is great - drop Cingular

10 years into the cell phone revolution the phones have gotten smaller, lighter with great features but what's the point when you can't carry on a conversation? I have found Cingular to be by far the worst in terms of dropped calls in the SF Bay Area. I suffered thru AT&T and their conversion to GSM and Cingular is not any better than that service no matter what they promise. Cingular also has very consumer unfriendly 2 yr. contracts that you will be paying on long after that shiny phone has lost its lustre. They are constantly changing their rollover minute plans to screw you out of your minutes. When i downgraded from a higher national plan to a lower national plan they took away all the minutes I aquired in a year. In other words maximize the revenue - minimize the service is their motto. I could live with this if i could make a decent phone call - i can't believe there are so many dead areas in a place with 13 million people.
