Well it worked fine the night the update was released, but now it only works when it wants to. I have it set to push my mentions and it only pushes them sometimes. In case anyone is wondering (because this was brought up on another forum) you still have to have a polling interval set to refresh the stream. I keep mine at 4 hours so it doesn't kill my battery.
Also, you can have it push all tweets but this too sounds like a great way to kill your battery so I haven't tried that option out.
