Answer: 
the API for Linkedin You can refer this :

You can use UIWebView to load twitter and facebook. It will let you exploit the entire functionality offered by these two Social networking sites. Though It's not impossible to build an application the way you want it to be but using webview will save your time as well as efforts. Since you are already aware of the FB and twitter integration so I am sure you are already aware as to what all we can do from iPhone application..viz.. Setting Status, reading POSTS etc.. I am not quite sure about Linkedin.. Just in case if you come across any solution for this let me also know about that.
