Apple’s online store last month mysteriously went offline for hours in what had been a slight tweak which saw a limited roll out of Facebook and Twitter sharing on the Mac Pro page and iPod classic pages. Today, the company rolled out the social sharing buttons for every product sold on the online store, including printers, accessories, speakers and other third-party products. It’s easy, just browse the store for a product you would like to share, click the right side of either the Select button or the big green Add To Cart button and then choose Twitter or Facebook to share.
