How to get "posted via blackberry" when I use to post on facebook from my BlackBerry device

I don't know if you can now, with the app is only a launcher, iPhone has lost that feature posting from their Facebook app ...

You can always type that line or add it as an autocomplete thing which automatically corrects it. For example, just use sigme and have it put "composed/posted from my blackberry X device" (doesn't have to be the way I typed it, but it'll work), and save the entry. Bingo.

The closest you can get to doint that possibly is using Face10.
There is technically no more Facebook "for BlackBerry" as it has recently lost support for the native application, and the best you can get out of the box is "posted via mobile".
