Senior Vice-President and Head of the Devices Hardware Engineering Department of Apple, Mark Papermaster, left the company, reported the New York Times.

Mr Papermaster came to Apple from IBM in 2008. In the new place he was responsible for iPod and iPhone development.

According to some observers, the reason of Mr Papermaster’s resign was the notorious problem with the iPhone 4 antenna, which made Apple start giving away free cases for this smartphone.

The former Vice-President didn’t comment his resign. The speaker from Apple, Steve Dowling, confirmed Mark Papermaster’s resign having mentioned that his duties passed to Bob Mansfield, Senior Vice-President and Head of the Mac Hardware Engineering Department.

By the way, Mr Papermaster didn’t take part in the conference dedicated to the ‘case distribution’. Steve Jobs, Bob Mansfield and the main operation director Tim Cook carry his can.

By the way, iPhone application development is probably the most rapidly developing trend in the sphere of mobile application development at present. So any change in the management may influence it.
