After launching its new 4G LTE service in Seattle days before the iPhone 5 launch, AT&T is now launching its faster data service in Tacoma, Washington, as well as Federal Way, Lakewood, Puyallup, and Auburn. Additionally, LTE expansion upgrades are now live in Seattle, Bothell, Bellevue, Kirkland, Edmonds, Lynnwood, Renton, Redmond, Tukwila, and Woodinville. AT&T plans to officially announce the enhancements tomorrow. Of course, you'll need an LTE-compatable AT&T device to take advantage of the faster speeds.
