Although iPhone 3GS has a commendable 3.2 megapixel camera, but apart from very basic camera functionality, you can hardly do anything special with it. But then as they says that there is an app for just about anything on the iPhone, so is the case with this app as well. A new app by the name of Security Cam has just been approved which enables iPhone users to use their iPhone as security (or should I say spy?) camera.
