Apple has yanked iChatr -- the chat-roulette-style app for iPhone 4 -- from the iTunes App Store.
If you're familiar with what goes on in these kinds of apps, the (predominantly male) nudity and sexual activity, then this probably doesn't come as much of a surprise. If you're not familiar, you probably downloaded it, became familiar quickly, and near instantly complained to Apple prompting the removal.
According to the developers, SKJM:
“The iChatr application has currently been removed from the App Store due to reports of a number of users exposing themselves during the random video chat sessions. We are currently discussing possible solutions to the problem with Apple.”
Jeff Scott from 148.apps adds:
