Via iOS Facebook status update?

[mani]

I recently got an iPhone 4s and on Facebook when I update my status
from my iPhone it just says ''via mobile'' I thought it was supposed to
say ''via iOS'' and it doesn't on mine for some strange reason. Why
would that be? Also when I update photos its supposed to put it in an
album called ''iOS photos'' on mine it just goes straight to ''mobile
uploads'' I know it's not important, but it just came to mind why mine does not say ''via iOS'' my aunty has an iPhone 4 and when she
updates status/photos it says ''via iOS'' And I use the Facebook app
from app store not the desktop version on safari or the app type
version on safari just the app itself
