How to get facebook status to say "Via Iphone"?

[Lynn87]

So i have an Iphone, and i got the facebook app from the app store. Yet when i do a status it still says,"sent from mobile". How do you get it to say "via Iphone" with a status?
thanks u guys. Omg thank you for pointing that out. No I never registered it yet. Let me try that and i'll let you know if it works.
Didnt work.My number is already registered on my facebook account. Do I have to register it again since i have an Iphone now? I had downloaded the facebook app from the app store and i updated my status from the app. Yet when i go look it still says "sent from mobile" sucks. Nothing seems to do the trick....
