In case anyone has downloaded some recent update for some App Store apps and they're now crashing, you may need to trash them and try a new download. Assuming that Apple has actually fixed the problem.

"Dozens of apps have been affected by the bug, including Angry Birds Space, Pinball Maniacs and Dolphin HS Browser…"

And some iOS Apps also affected it seems:

And more with a Google search…

It'd be nice if they provided a list of the affected apps.

Maybe Apple doesn't even know, but I guess any affected user of such affected "updated" App Store apps will. :(

Apple has acknowledged the problem in a post to the Developer forums, and are working on it.

UPDATE: Apple Says it Has Fixed Server Bug Led to Crashing Apps (http://allthingsd.com/20120705/apple-says-it-has-fixed-server-bug-led-to-crashing-apps/)

I wonder if the Kijiji app is one of them.. that stupid app crashes on me all the time.. total POS.

Isn't the Kijiji app an iOS app that's known to be buggy? And maybe not really related to this subject post.

Oh, 'Apple' app store... I thought the articles were about the iTunes app store. I've never used the other app store, so it didn't even occur to me it wasn't related.
