NEW YORK (AP) - On the same day it started taking pre-orders for the iPhone, Verizon Wireless is updating its terms of service to give it the right to slow down data service for users who use far more than others.
A document on the company's website says subscribers who sign a new contract for an unlimited data plan - a requirement to buy a Verizon iPhone - are agreeing that the carrier may throttle their data speeds if they start they use so much that it slows down service for other users.
Heavy data use from iPhone users has caused congestion and poor service in some places on AT&T's network,.
But Verizon Wireless spokesman Jeffrey Nelson says Verizon's move isn't related to the launch of the iPhone.
