Android and PlayStation Vita owners have felt the Music Unlimited love on their respective devices for quite some time now, but the Spotify / MOG / Rdio competitor has finally made its way to the App Store, bringing with it yet another option for streaming music on iOS. The free app appears to be optimized for iPhone and iPod touch (though it's also compatible with iPad), and will enable on-the-go jammin' with a $4-per-month Basic subscription over 3G, 4G or WiFi connections. You can pull in tunes from the millions of tracks in Sony's collection, or access songs on your PC using the Music Sync service. The app is currently only available in the New Zealand App Store, but it's expected to hit other Music Unlimited countries soon. For now, you can hit up the source link for the Kiwi App Store preview, or head over to the Music Unlimited site to sign up.
