The App Store has been a huge success for Apple and for some developers, but there have been a few hiccups along the way. Apps have made it past Apple's rigorous reviews machine only to be pulled down permanently, or have their developers required to remove key features.

We've rounded up 10 of the most notable pulls (along with one that had to be tweaked for less functionality). Click the slideshow link below to get started.
