I doubt the Verizon "unlimited" claim is sincere. Let me explain why.<p>When Verizon rolled out its 3G data plan (EVDO Rev.0) in 2005, they <i>initially</i> sold an "unlimited" plan. Very few smart phones could do EVDO, so it was mostly the sale of USB dongles for use with laptops and similar.<p>In 2006, Verizon started terminating "abusive" users for downloading too much on their supposed "unlimited" plan, and after much wrangling, Verizon finally declared that using more than 5GByte/Month of network traffic is their line in the sand for "abuse."<p>The above resulted in a class action suit for false advertising. The way Verizon resolved the dispute is not very well known. They simply changed the terms for new customers so new customers would pay per KB fees for everything in excess of 5GByte, and the new accounts were no longer advertised as "unlimited."<p>The old customers were allowed to keep their "unlimited" status and use the connection as much as they want, but if transfers got too far past 5GByte, the connection would be throttled back to a slower speed. As the saying goes, the old customers were "grandfathered in" with basically the old terms. --The reason, of course, after a few years is most people would make changes to their account, like accepting a "free" new phone/dongle offer, and create a new contract under the new LIMITED terms.<p>Since I was an early adopter, I have an old "unlimited" account. I refuse to change the account, so it remains unlimited. Only on very rare occasion do I see it get throttled for a few days until the billing cycle ends.<p>With the new iPhone offering, Verizon might be using the same "unlimited" tricks to get early adopters. It will be interesting to see how this works out...<p>EDIT: precafinated typos
