In a bid to expose new customers to its service, Audible's ( ADBL) digital audio content will be preloaded with a new line of smartphones, the company said Monday. Sony Ericsson, a joint venture between Sony ( SNE) and Ericsson ( ERICY) will pack three of its new phones with the service. The content can be accessed over-the-air, through a wireless connection or as a download. Sony Ericsson customers will receive a free 30-day trial of the service. As part of the agreement, Audible will also give Sony Ericsson customers five-minute samples of select audio books in French, German, English and Spanish from works by Stephen King, John Grisham and Sue Monk Kidd, among others. "This type of application benefits not only our W950 Walkman phone with its powerful media player, but the P990 and M600 phones as well, as different audiobook and news content can be targeted toward more business-oriented audiences," Ulf Wretling, director of content planning and management at Sony Ericsson, said in a statement. Audible shares rose early in the day on the news. In recent trading, the stock was off 3 cents to $8.55.
