As an alternative, Portland-based Urban Airship now sells and hosts an In-App Purchase infrastructure, in addition to Push Notification services.

A thought for you: how do you persist the “unlocked” state from one launch to another? You could write a .plist, a database record, or other local file, but that struck me as rather hackable by the pirate/jailbreak crowd.

The problem with this line of thinking is that everything is rather hackable by the pirate/jailbreak crowd, and that they do not pay money for your software anyhow. Drop it in a file and spend the extra engineering resources you just saved on something which will help you market the app.

I'm surprised it took him so long to get it together (he recommends a month.)

I created an entire app in less than two days that has consumable in app purchases. It has a RoR server component as well as the iPhone component and supports the asynchronous callbacks and such. Maybe it was easier for me because my background is in server side programming?

It sounds like he hit a fair amount of trouble with subscriptions.

From my look at his article, he's doing everything clientside, which is causing him the extra headaches about restoring stuff.
