Earlier this morning, reports started to come out stating that the Apple App Store is pushing corrupt binary's to its users (both Mac OS X and iOS). Of course this caused instant crashes of the affected apps, leaving users with a big question mark inside their heads. Marco Arment, of Instapaper fame, was one of the first to notice and very vocal, bringing the issue to the attention of many in the media and at Apple.
The list of affected apps is pretty surprising, with titles such as Angry Birds Space, Yahoo! Search, Google Reader and, Instapaper. The number of developers affected now tops 115, and probably counting.
For the first several hours Apple was quiet on the issue, but it has finally acknowledged the problem in the support forums and even reached out to developers via email. Suspicions seem to be that the FairPlay DRM is at the root, but no one is pointing fingers on that until there is an official answer. Apple is working (I hope very fast) on a fix, which will hopefully be delivered sooner, rather than later.
In the mean time, how about you buy Developer's apps from their own websites. I say this because the developer would get all of the money, because naturally Apple is going to take a cut for the app being on their store.
I also wanted to point out to not star an app right now as it can be affected during this App Store "snafu".
