LG unveiled its latest LTE smartphone today, the Optimus LTE Tag. The Tag is the company's next addition to the Optimus family, and includes an LG Tag+ feature that uses NFC to communicate with physical stickers (tags) that operate the phone's settings. LG will supply tags that can be placed in an office or a car dashboard to activate specific settings for various scenarios. An office worker may want to mute a device after entering a building, while a commuter could swipe a tag to turn on Bluetooth and GPS in car mode.

The Optimus LTE Tag will be available in white and includes a 1.2GHz dual-core processor, 4.3-inch display, 5-megapixel camera and Android 2.3 Gingerbread. LG says it will offer the option to upgrade the Tag to Android 4.0 Ice Cream Sandwich in the future. LG announced Korean availability today, but there is no word on any plans for other countries. The Optimus LTE, released in October last year, is currently available in the US, Canada, Japan, and South Korea, so it's possible that the Tag will make its way to these markets soon too.
