Looks like Apple has also bowed to political pressure. From Tech Crunch:
Looks like an unofficial iPhone and iPadapp that let you view WikiLeaks site content and follow the WikiLeaks Twitter account on the go has been removed from the App app store earlier today. The app used to be available here (here’s the Google cache).
The crazy thing is, the more corporations and governments shun WikiLeaks, the more powerful it becomes. Having said that, I'm disappointed in Apple for showing absolutely no spine when it comes to such an important issue.
