Are you wondering what the music service on Sony’s upcoming PlayStation Phone might look like? PSP owners will soon have access to what may be the best indication yet of things to come. Sony announced earlier this week that a new software update, version 6.35, would prepare the PSP for the Sony’s upcoming “Music Unlimited powered by Qriocity” service — which bears a name so ill-conceived that even Sony apologetically wraps it with quotes. Like Zune, Rhapsody, Napster and countless other services, Music Unlimited will be a cloud-based product that allows subscribers to stream music on demand to compatible devices. The service will launch soon and when it does, Sony’s PSP will be ready and waiting.
