Announced by Trent Reznor via Twitter, the Nine Inch Nails iPhone app we recently reported on is finally out in the iTunes store. As previously mentioned, the app is free. Wired has a nice article about the app and it’s implications. Having just downloaded it, we can tell you that there is incredible depth and amazing features available on this app – clearly a great deal of time was spent on developing this. Despite using the app just briefly, we are still convinced that this will be seen as a redefining moment in the way that successful artists communicate with their fans in the very near future.
