No it's not. It's because your hitting the Messages button, it has nothing to do with a swipe. All buttons are pressed hwen you release your finger. Start on the button and swipe across and release after your finger is off the button, does it work now? No.
Ass.
It does work, it's just not a particularly exciting feature. Also, I think the OP said 'ACTUAL' because most of the features that are touted as being hidden around here are ACTUALLY not.
