My friend has this phone (I believe), and I notice on my Samsung Charge (when on stock or rooted with ROM), the Facebook app has the option to share a photo via "Messaging", a green icon. Then I'm able to send the photo via MMS? to a contact

On my friend's phone, he has no such option. Though, there is a "Messages" app (white icon with blue), but that doesn't even show in the share menu. How can I get that to show in the Share list for him?
