AT&T announced a new service today to help retailers design, deploy and manage mobile commerce Web sites, as well as applications optimized for smartphones.

Called Digby Mobile Commerce from AT&T, the new service will allow smartphone users to search, browse and buy products on smartphones running various operating systems. Combining the new service with AT&T's existing Mobile Barcode Services will allow retailers to provide information, product photos, rich media and other enhancements when a customer scans a barcode while shopping.

Chris Hill, vice president of advanced mobility solutions at AT&T, said the Digby Mobile Commerce addition will give retailers a comprehensive set of services for marketing and selling through smartphones and other mobile devices.

AT&T partnered with Digby to offer the service, although pricing was not announced. The service is available today and AT&T has offered more details on its Web site .
