Sprint has announced that it will slow down data speeds for its most demanding smartphone customers beginning next month. The carrier is currently sending out text messages to subscribers alerting them of the change, which will only apply to areas dealing with network congestion. Anyone that falls within the top 5 percent of data users will start seeing throttled speeds the following month, though Sprint isn't getting specific about just how hard it'll be hitting the brakes. The company only says that affected customers can expect "slower-than-normal data speeds until the congestion has passed." Sprint clearly isn't too fond of these data-hungry users; in a FAQ on its website, the carrier bluntly states that they "consume a disproportionate share of network resources and cause a negative user experience for the rest."
