Today is iOS 6 day and the latest mobile OS from Apple will be released at 1 PM ET (10 AM PT), says a report by Absinthe Jailbreak's Gamel Sabry. His post also has a timetable that lists the launch time for each time zone worldwide.
iOS owners can look for the over-the-air update by going to "Settings > General> Software Update" or by connecting their device to iTunes. Be patient as the rush to download the update usually slows the update process to a crawl.
