AT&T announced on Thursday that it now has a policy for throttling users on unlimited data plans. According to an AT&T statement relayed by Ars Technica, the wireless carrier will begin to throttle customers with a 3G/HSPA+ handset at 3 GB and 4G LTE handset owners at 5 GB. This new 3 GB soft cap will affect iPhone owners who have clung to their unlimited plan.

This change in policy follows a recent small claims court lawsuit in which iPhone owner Matt Spaccarelli was awarded $850 for being throttled at 2 GB on an unlimited plan.
