US Cellular's LTE selection just gained an additional member: the Samsung Galaxy Metrix 4G. Available online today for $179 after a $100 mail-in rebate, the device comes with fairly middle-of-the-road features, such as:

• A slide-out QWERTY keyboard
• A 1GHz processor
• A 4.0-inch touchscreen
• A  5MP rear-facing camera and camcorder
• A front-facing camera

In an effort to promote its LTE network, the carrier will be lowering the handset's price to a somewhat more reasonable $129 (also after a mail-in rebate) in markets where 4G is either currently available or will be accessible by the end of the year.
