AT&T LTEAT&T is on a mission. After releasing their first two LTE enabled smartphones just this month, the company is introducing the next generation of mobile speeds to six additional markets, bringing its total to 15 nationwide. What else? Well, how about a brand new and exclusive 4G LTE Samsung Galaxy Tab 8.9?

AT&T promised they’d bring proper LTE to 15 markets before 2011 came to a close, and that’s exactly what its doing. The six new markets slated to receive LTE goodness include Charlotte, Indianapolis, Kansas City, Las Vegas, Oklahoma City and San Juan, Puerto Rico, and will roll out coverage on November 20. Will more LTE equal more data plans being activated before the year’s up? Maybe! AT&T says that for a limited time consumers who purchase the $479.99 Samsung Galaxy Tab 8.9 will get a Samsung Galaxy S II Skyrocket or Samsung Galaxy S II for free – the catch is both need to be activated with a two-year contract. Still, it’s a tempting offer heading in the holiday season.

Unfortunately, cities like Los Angeles, New York and San Francisco are still absent from AT&T’s 4G LTE coverage list. With the aggressive roll out plan the company is adopting, it’s probably not long before we see more 4G LTE love across the nation.

Interested in Samsung’s Galaxy Tab 8.9? Aside from sporting 4G LTE, the Galaxy Tab 8.9 comes loaded with Android 3.2 (Honeycomb), 3.2 megapixel rear facing camera, 2 megapixel front, Snapdragon 1.5GHz dual-core processor, 16GB of internal memory (expandable to 32GB via accessory option), 1GB RAM and TouchWiz UX.
