Want your own iPhone application? It can be an expensive business, but Mobile Roadie is aiming to help. It offers a self-service platform for creating such apps, aimed at independent labels and artists. The apps cost $299 plus a $29 monthly subscription fee, although The Orchard has apparently negotiated a discount for its members, according to Hypebot. The apps can be updated with music, photos, video, news and tour dates at any time.
