U.S. Cellular let us know that on Thanksgiving U.S. Cellular is offering a one-day, web-only promotion for customers looking to switch to U.S. Cellular and current customers who want to add a new line to their service. The BlackBerry Torch 9850 will be free after a $100 mail-in rebate. U.S. Cellular is also waiving the activation fee and providing free shipping.

In addition to getting a free phone now, new customers can also join the only rewards program in wireless and be well on their way to a second free phone with the 2,000 point bonus they receive when they sign up for “My Account” within 14 days of starting service. Current U.S. Cellular customers who add additional lines will also receive the 2,000 point bonus. Customers on Belief Plans are recognized for their loyalty and get points for doing simple things like paying their wireless bill on time, adding a line or referring friends and family. Points can be used for new phones faster, accessories, ringtones and monthly service charges.

More information will be available tomorrow at uscellular.com.
