A good mobile retail study from millenial media via Cynopsis. Hope this is helpful:
Mobile applications and browsers are becoming essential sales and marketing tools for retailers, according to a new whitepaper from mobile ad network Millennial Media. Consumers rely on their mobile devices to guide them through every step of the purchase process, from determining if they need a product (52% of respondents), to making a purchase (38%), to evaluating a product post-purchase (12%). Over 13 million consumers accessed retail content on their mobile phone in a given month, with 2.2 million accessing some sort of retail content almost every day. Retail was the top vertical on the Millennial network both globally and in the U.S. From Q1 2010 to Q1 2011, retail spending grew over 1300%.
