The launch of iTunes Match has been promised in the next 11 days, but frustratingly Apple has already added an iTunes Match on/off switch in iOS 5. Found under the Settings icon in the Music section, users who turn the switch on are asked to sign up. But that just nets a message: "You are not currently subscribed to iTunes Match. Use iTunes on your computer to subscribe.” On iTunes itself, the message is still "Coming Soon".
