Most iPhone developers who grab a copy of the iPhone SDK from Apple’s iPhone developer website will get a copy of the latest SDK and pre-release 2.1 firmware without support for the upcoming Push Notification feature.
It looks like some developers, however, are a bit luckier than the rest of us and already have a copy of the new Push Notification API to start playing with.
I’m curious to see how developers take advantage of this. It’s interesting how Apple plans to implement it. As you might recall, Apple announced at this years WWDC that when Push Notification arrives it won’t allow applications to run in the background which is how it’s typically done. Instead, the applications will register itself with a background notification service–a “hotel operator”–that will distribute notifications that come in.
