After launching on iOS and Android almost a year ago, the mobile version of Redbox Instant by Verizon has finally arrived in the Windows Phone Store. Aside from a few cosmetic changes and added Live Tile support, the new app works exactly like its cross-platform counterparts, offering movie streaming and maps to nearby Redbox kiosks. An $8 monthly subscription also covers the rental fees for up to four DVDs, although customers can upgrade to Blu-ray discs for an additional dollar. The bad news is that the app's exclusive to Nokia's Lumia range right now -- plebes with other WP8 devices will have to wait until the end of January for general availability.
