Interoperability of Facebook apps could work only on Android
"We plan to start by making it possible for you to send messages to your contacts using any of our services, and then to extend that interoperability to SMS too. Of course, this would be opt-in and you will be able to keep your accounts separate if you'd like," Zuckerberg wrote in a blog post on Thursday.
