The iChatr App Brings Chatroulette-Style Mischief to Your iPhone 4 The iChatr iPhone app is as exciting as it is terrifying. Why? Because it's basically Chatroulette for your iPhone. The app is free, but does require an iPhone 4. All you do is connect to your Wi-Fi network, open the app, and swipe through chat partners like the lady in the photo. I just hope that, unlike her, you don't encounter too many weird-looking guysor wanking ones. [iTunesThanks, Scaughtt!] Send an email to Rosa Golijan, the author of this post, at email@example.com.
