Droid-Life that should be changing today.
Galaxy Nexus -- and that is the LED notification light. Something so simple, small, and cheap makes a world of difference. Especially for people like me getting notifications and work emails all day long. For those wanting to get the most out of this awesome feature we have just the app for you.
Android Market and it only shows a few small bug fixes and ICS support. This is just in time because I'm sure many are picking their Nexus up at this very moment.
