AT&T is set to begin throttling the speed of the top five percent of heaviest data users beginning Saturday, October 1st. Even users with grandfathered "unlimted" data plans will experience reduced speeds once their usage puts them in the top five percent, but the throttling will end at the end of the billing cycle until the user once again uses too much data, said the company. A Reddit user showed 9to5Mac a text warning he got from his provider as proof.
