Thanks to a little something called competition, Verizon Wireless was forced recently to bring back unlimited data plans, after spending the last few years trying to tell consumers they neither wanted nor needed such plans (narrator: they did). But all has not been well in Verizon-land since, with several network performance reports indicating that Verizon's network configuration was struggling a little under the load of these new unlimited users. That's a problem for a company that justifies its higher prices by insisting it offers the best-available wireless network.

A few weeks back, customers complained when Verizon began throttling YouTube and Netflix customers without telling anybody, only to subsequently admit they were conducting a "test." Fast forward to this week, and Verizon Wireless has announced a complete revamp of its "unlimited" data plans that severely restrict how your mobile connection can be used.
