4. Facebook App For iPad Causes More Problems:

In 2010, Jobs visited Mark to discuss about Facebook iPad application. Zuckerberg had promised to create their first tablet app with iPad.

An apple employee says, “Roughly three months ago, Steve Jobs — then the Apple CEO — paid a visit to Facebook to discuss a Facebook for iPad application with CEO Mark Zuckerberg. Zuckerberg promised Jobs that the social network would release its first ever tablet application for iPad.”

Jobs later got to know that Facebook had already developed an app for HP’s TouchPad, Apple’s rival. Needless to say Jobs was furious. Mark then tried to pacify the situation by asking Jon Rubinstein at HP to remove the FB app. HP refused to comply and Mark ended up freezing HP’s access to FB’s API.
