Southern California judge has awarded US$850 to an iPhone user because AT&T Inc. reduced his download speeds in an attempt to manage usage on its network, reports the “Associated Press” (http://macte.ch/vFvr8).

Pro-tem Judge Russell Nadel found in favor of Matt Spaccarelli in Ventura Superior Court in Simi Valley. Spaccarelli filed a small claims case against AT&T last month, arguing the communications giant unfairly slows speeds on his iPhone 4’s unlimited data plan.

The “Associated Press” notes that Nadel’s ruling could pave the way for others to follow suit. AT&T has some 17 million customers with “unlimited data” plans that can be subject to throttling.
