Facebook says it’s currently working with AT&T, Deutsche Telekom, Orange, Telefónica, T-Mobile USA, Verizon, Vodafone, KDDI and Softbank to introduce operator billing. This would enable Facebook users to buy digital goods via a mobile web application and pay by charging the purchase to their mobile phone account.
The social network has also said it’ll soon offer Open Graph connections to Android apps; an option that’s already available to iOS and mobile web apps. This lets customers share information on Facebook from within a mobile app.
