As you might recall from when the Oyo was launched last fall, Thalia had promised a 3G equipped model. I was just sent a link to the pre-order page for the Oyo 3G on the Thalia website. It's shipping on 10 February with a retail of 189 €.
The Oyo is based on a 6" Sipix screen and is tied to one of several ebookstores (Thalia, Empik, FNAC). This model sold by Thalia will of course use the Thalia ebookstore. Browsing the ebookstore is free; other web access will cost extra (probably).
