AT&T let the Federal Communications Commission know in a letter to Commissioner Robert McDowell who had asked about AT&T's policy regarding P2P traffic over its wireless network at an FCC forum in Pittsburgh on July 21. AT&T says it does not use "network management tools to block the use of P2P applications by its mobile wireless broadband customers." Instead, he said the company warns customers in writing that they would jeopardize their relationship with AT&T Wireless if they were caught using banned P2P applications. "A small number of users of P2P file sharing applications served by a particular cell site could severely degrade the service quality enjoyed by all customers," the letter reads.
