We recently launched LinkedIn Intro — a new product that shows you LinkedIn profiles, right inside the native iPhone mail client. That’s right: we have extended Apple’s built-in iOS Mail app, a feat that many people consider to be impossible. This post is a short summary of how Intro works, and some of the ways we bent technology to our will.As pointed out by many — it’s a man-in-the-middle IMAP proxy that gets automatically configured by installing security profiles for iOS.

While I love the approach of hacking proxy server to bend request/response at your will, I don’t believe a company like LinkedIn should do this, and Apple might take action to prevent things like this, since allowing to install this kind of profile could lead to a malicious application easily.
