The launch of Apple's iTunes Match should be coming any time now — yesterday, Apple deleted all iTunes Match Beta accounts that developers have been testing, in an effort to "improve the overall quality and reliability" of the service. Apple claimed at its October 4th "Let's Talk iPhone" event that iTunes Match would launch by the end of this month, and time's getting short if it is going to deliver on that promise. Fortunately for those interested in trying this new service, evidence has been mounting that the launch is imminent. There's a "coming soon" label in the iTunes application, iTunes Match setting are appearing on iOS 5 devices, and now Apple's doing some final housekeeping on its cloud before allowing users to start uploading their music.
