Aaaaaaaaand the price keeps falling
Amazon.com: HTC ThunderBolt 4G Android Phone (Verizon Wireless): Cell Phones & Accessories
$129 on a new 2-year contract.
It ain't Droid X cheap (it's free on contract), but still the cheapest I've seen it!
you can return it (you have 3 days to return without a $35 restocking fee)....but this deal isn't through verizon. you have to buy through amazon (or whoever it's through).
There is a separate Amazon ETF on top of the Verizon one:
AmazonWireless Instant Discount Policy
When you purchase your device with service from AmazonWireless.com, we automatically pass along an instant discount from the carrier to you. This discount has been provided to you based on your agreement to (a) activate a new, or extend an existing, line of service for this device with the carrier, and (b) maintain this service in good standing for a minimum of 181 consecutive days. If you do not activate or extend a line of service in connection with this device, or if your service is canceled/disconnected before 181 consecutive days, AmazonWireless.com will charge you $250 per device, plus applicable taxes.
This is why I passed on this and just went straight to Verizon.
