Apple predicted to introduce lower cost iPhone models in June

Katy Huberty with Morgan Stanley maintains that the biggest barrier to greater iPhone adoption is the cost of the hardware, followed by the service plan. The investment in the device has been its biggest issue in both developed markets like the U.S. and emerging ones like China.

But Huberty expects Apple to address that in June, by introducing a new model that will be economically friendly to even more consumers.

"We expect Apple to launch new iPhones in June that offer both a lower total cost of ownership and new functionality, potentially including gesture-based technology," she wrote in a new note to investors Friday.

In 2009, when Apple introduced the new iPhone 3GS, the company also dropped the price of the previous year's iPhone 3G to $99. However, despite the lower price point, the high end iPhone 3GS was still the most popular option for consumers.

In addition to lower cost of ownership for the iPhone, Huberty remains bullish on AAPL stock because of the forthcoming iPad launch in March. Here she is particularly optimistic, projecting shipments of 6 million devices in the 2010 calendar year, versus Wall Street's average projections of 3 million to 4 million.

"We expect Apple to ship its first iPad and announce additional content deals in late March to better than expected demand," Huberty wrote. "We see the iPad targeting the sub-$800 consumer notebook market which equates to 30M annual units just in the US (120M globally."

Morgan Stanley has maintained its "overweight" rating for AAPL stock, with a price target of $250.

In the past, Huberty was notoriously negative on AAPL stock, suggesting the iPhone was too expensive even at a $199 price point. In late 2008, she predicted that iPhone sales would suffer because Apple had priced the product too high.

But last year, Huberty turned positive on Apple, stating that the company had become the "clear leader in the battle over the mobile Internet."
