"Verizon Wireless strives to provide customers the best experience when using our network, a shared resource among tens of millions of customers. To help achieve this, if you use an extraordinary amount of data and fall within the top 5 percent of Verizon Wireless data users we may reduce your data throughput speeds periodically for the remainder of your then current and immediately following billing cycle to ensure high quality network performance for other users at locations and times of peak demand. Our proactive management of the Verizon Wireless network is designed to ensure that the remaining 95 percent of data customers aren't negatively affected by the inordinate data consumption of just a few users."

Nice timing, Verizon. Just as thousands -- possibly-- of smartphone users are pondering the switch to Big Red for Apple's iPhone 4 , the carrier has slipped in two critical policy changes that are apparently effective immediately. Tucked within loads of fine print in a new PDF that surfaced on the company's site, there's this:To our knowledge, this is the first time that VZW has taken a notable position on throttling, and the link to its stance on net neutrality (as it applies to wireless, anyway) is fairly obvious. What's most interesting to us is the five percent of data users figure; the top one or two percent isn't a huge amount, and there's a good chance that bandwidth abusers are up in that echelon. But we're guessing that quite a few business travelers will fall within this particular range, and given that VZW now holds the right to throttle data for your existing billing cyclethe next one... well, good luck gritting your teeth and lasting through that two-year contract.In related news, the company is also implementing optimization and transcoding technologies in its network, which is a politically correct way of explaining that it can downres any multimedia you try to send through Verizon's pipes.
