There were over 50 million smartphone owners in the U.S. during the three months ending in July. That's up 11 percent from the corresponding April period. RIM was the leading seller with a 40 percent market share, followed by Apple with 24 percent share. While consumers choose between the BlackBerry and iPhone, the battle between the two cellphone makers is also escalating.

BlackBerry's biggest problem may be an Apple, or more specifically, Apple's increasingly popular iPhone.

Kara Rubin just handed in her work BlackBerry for good.

Kara Rubin said "My work just gave me an iPhone 4 to replace the Blackberry I use for work."

The loss of corporate clients is a big concern among analysts.

BlackBerry maker Research In Motion announced second quarter earnings that beat estimates. But beneath the headlines there are signs U.S. growth is slowing, just as competition is increasing.

David Carnoy, Executive Editor at CNET.com:

David Carnoy, Executive Editor of CNET.com said "Expanding into the consumer market and making that phone be a real multi-media fun phone with apps and all that stuff is really going to be a challenge for BlackBerry and also retaining those corporate customers. As long as it can keep those corporate customers it's going to be okay going forward."

The BlackBerry Torch, a touchscreen device with a slideout keypad, was intended to ignite sales and excitement among consumers. Launched last quarter, it failed to make much of a sales spark while devices powered by Google's Android software, and the Apple iPhone 4 continue to win over customers.

Carnoy says BlackBerry's keyboard is a big draw for users. But there's competition ahead:

David Carnoy said "Apple is pretty much always going to have the virtual keyboard but there's a lot of Android devices out there that are going to have both the physical keyboard and the virtual, a touchscreen, so I think that Android is really a big worry for BlackBerry at this point."

RIM's international growth helped mask some of the weakness in North America last quarter. And recent issues with some foreign governments over its encrypted data are expected to be resolved soon.

The company also offered stronger guidance for the current quarter, suggesting to some analysts that BlackBerry is far from dead.
