Best way to get faster speeds

I was curious as to the best way to attempt to get at&t to bring updated infrastructure to neighborhoods. My city apparently at some time in the past could get uverse, but many blocks such as my own are told we can only get 5 mbps plans. Now I dont expect to get fiber, even though we were listed in the pilot pamphlet for it, but it would be nice to get faster speeds. I was explained, internet speed is related to how far away you are located from the box, but what else goes into it? Is there a formal petition to get new infrastructure for faster speeds? Or should I be quiet and just go back to despicable cable internet?
