Happy fifth birthday, iPhone!

Whitney Bluestein, Bluestein & Associates, appeared on CNBC Friday to weigh in on Apple’s iPhone, which celebrates its fifth birthday today.

Over the past five years the iPhone has quickly moved to a position of dominance in the smart phone market, Bluestein said.

Five years ago, when the iPhone was first introduced, Nokia had 50 percent of the market for cell phones and BlackBerry maker Research In Motion was in second place with 10 percent of the market.

Today, by contrast, Apple accounts for 73 percent of the global profits from handsets, with Samsung and everyone else “fighting over crumbs,” Bluestein said.

Research In Motion’s days now look numbered after the company reported worse-than expected quarterly results Thursday and delayed the launch of its next BlackBerry device to early 2013 from late this year.
