If you just received a Galaxy S III or a Note II this holiday season, you could do yourself a favor and register it on Samsung's Facebook page to get even more goodies from Santa Sammy. What do you get in exchange for handing over some personal details and giving the Korean company access to your timeline? Why, a free flip cover and six TecTiles, which usually go for about $15 for a pack of five. We haven't heard much about wide adoption of these programmable NFC tags, but maybe it'll gain some traction after a recent 3.0 app update and this promotional giveaway. We're not sure why the offer doesn't extend to other Samsung phones, but maybe they just don't have enough of those pastel covers to go around.
