[EDIT: Discontinued, all except Urban Airship.]
(Alright, this isn’t a “roundup” as we post this, since it’s pretty much just the links from this fine, fine post at NSCoriolisBlog — but hey, we’ll be editing as developments occur!)
So as you’ve noticed no doubt if you’ve even cursorily looked at how to go about implementing push notifications or in-app purchasing in your sparkly new cutting-edge iPhone apps … there’s a lot to do there. More importantly, you can’t just toss your binary up to Apple and forget about it any more, there’s ongoing service and scalability issues. That’s a pretty big leap in project complexity. However, there are services that are springing up to take care of the hassles for you! The two that are actively deployed and providing push and purchase both are
Urban Airship — got all the big name clients so far
iLime — make a big production about being cheaper for messages
Both charge 5 cents a download for content, it seems.
As well, there’s several upcoming competitors in beta:
[EDIT: AppNotify — thanks, Josh!]
Seems like a few too many gearing up there for what the size of the market is likely to be. So although in line with the programmer’s natural desire to avoid work we thoroughly recommend getting started with one of these services, we suspect that if we actually ended up depending for our livelihood on a particular product we’d want to go through the trouble of getting our own host set up to remove this possible point of failure, at least unless/until one of them is clearly profitable enough to stick around for the long term. And so, here’s some links to help you out with that:

And again, our grateful acknowledgement to NSCoriolisBlog for providing all the links for the first edition of this “roundup”!
