"Each of the national wireless carriers has mostly or completely ignored repeated FCC requests to submit network coverage maps and other information about their quality of service and service availability." See Breaking Up Is Hard to Do: Consumer Switching Costs in the U.S. Marketplace for Wireless Telephone Service
The FCC is a joke. They're mud. Ever since Michael Powell was in charge things went to pot. At best they don't enforce the laws they have and at worst they actively try and remove the laws that don't benefit their corporate overlords. Kevin Martin is almost as bad as Powell. Someone needs to clean house in that agency because their recent track record of deregulation is appalling. It's as though everyone on the commission is taking bribes from Newscorp and other big media conglomerates.
Well if you can get the carriers and other special intrest groups out of the back pockets of these officials, maybe they you would see changes.
