AT&T has announced it will begin selling the Amazon Kindle 3G in its retail stores nationwide as of March 6, 2011. AT&T will also include Kindle 3G in its connected devices displays, allowing customers to test drive the device onsite. The Wi-Fi only version will not be available from the provider.

The 6-inch Kindle 3G connects over Wi-Fi as well as AT&T's mobile broadband network to wirelessly download books, magazines, newspapers, blogs, and personal documents. The latest revision of the Kindle 3G boasts the advanced paper-like Pearl E Ink display, storage for 3,500 books, up to one full month of battery life with the wireless off, no monthly wireless fees or annual contracts, and a $190 price tag. The Kindle Store now has more than 810,000 books, over 670,000 of which are $10 or less. The best part is Amazon's Whispersync technology, which saves and synchronizes your full library of books, bookmarks, last page read, highlights, and annotations across all of your Kindles and Kindle apps for the iPad, iPod touch, iPhone, Mac, PC, BlackBerry, Windows Phone, and Android-based devices.

"As the first dedicated eReader offered in our stores, we are confident the Kindle will be an attractive addition to our in store connected devices lineup."
