Here’s Twitter’s statement on the matter:
We’ve been testing push notifications internally. When we launched Twitter for iPad, there was a configuration error that caused us to offer push messages to a small set of users. We’ve stopped sending push messages, but users may see an option to turn on push until we release an updated version of the app. So, push isn’t ready yet but we look forward to rolling this out soon.
I’ve asked Twitter to clarify what exactly is getting pushed. I assume DMs and @replies are two options, but it will be interesting if search items or specific lists are options as well. Twitter hasn’t gotten back to me on that just yet.
Currently, a few third-party apps enable Push Notifications for Twitter, notably, Boxcar and Notifo (via Push.ly).
[thanks Nick]
