So to be more specific, there were three tiers - free, which was limited to a certain number of plays per month and had ads, computer only; unlimited, which had unlimited (shocker!) plays, and no ads, computer only; and then premium which added high quality streams and the ability to listen on mobile. Now the free tier gets mobile streaming, with ads... will unlimited tier get mobile streaming without ads? I'd give it a shot, but I opened up my copy of the (absolutely terrible, IMO) iOS app, and it's just making me dizzy with an ad for premium and not letting me in. Oh well.
