SEATTLE – (NYSE: S) on Monday said has made a multiyear deal with a startup called Skiff for a thin electronic-book reader that operates over Sprint’s high-speed 3G network as well as Wi-Fi.

The will have an 11.5-inch screen, larger than those on competing devices including Amazon.com Inc.’s Kindle, Sony Corp.’s Reader and Barnes & Noble Inc.’s Nook.

Sprint and Skiff tout the device as the thinnest to date, at just over a quarter of an inch thick. The reader’s entire page will be a touch screen, unlike the Kindle, which uses physical buttons for navigation, or the Nook, which has a small built-in touch screen separate from the book page.

The Skiff Reader will connect to its own online content store. Skiff said it is also working with other electronics manufacturers to put its technology into a variety of devices.

The companies are planning to demonstrate the device at this week’s International Consumer Electronics Show in Las Vegas. Its price and availability date were not disclosed.
