Facebook has decided to upgrade and revamp its messaging system. Not only do you get messages, you can also get e-mails. And now, it's offering every one of its registered members to update their status and send messages/e-mails within their Facebook network using their cellphones without having to use a third-party provider.
You will see the prompt to edit your preferences when you log in again. I also just tested it using my Sun Cellular network and it works. Micro-blogging at your fingertips indeed!
I guess fathers will be using this one for birth announcements from now on... My husband used Twitter (which was tied to his Facebook account) when I gave birth last November.
