Welcome to this morning's edition of "First To Know," a series in which we keep you in the know on what's happening in the digital world.
Today, we're looking at three particularly interesting stories. A new iOS app called Knock is based around an extremely simple concept: one knock on your iPhone (models 4S and newer). The simple gesture grants access into your locked MacBook. A new report addresses the question of whether people are more interested in wrist technology like the Pebble and Galaxy Gear smartwatches or face technology like Google Glass. And Los Angeles residents might soon experience a major boost in Internet speeds.
