Samsung is running a promotion on its official Facebook page that lets Galaxy Note 2 and Galaxy SIII (S3) users get their hands on a free flip cover and set of 6 TecTiles for registering their device. All you have to do is head to the Samsung Facebook page, click the "Holiday Offers" button and then follow through to register your device. While quantities last, you can get some free swag for giving Samsung a little information about yourself. You'll need an active Facebook account and authorize the Samsung "app" for your page, but that's about it.
Registering your phone with the manufacturer may already be something you want to do, so might as well get something free for it, right? Head to the source links below to get your own.
