As reported earlier this week, Apple's Fifth Avenue store in New York City has shut down overnight -- a rare occurrence at the normally 24-hour location -- in preparation for the formal unveiling of the remodelled store's iconic glass cube, which appears to be scheduled for 10 a.m. Friday morning, according to a note on the store's web page. MacRumors reports that workers have removed a portion of the white covering that is below the fence level of the renovated store.
