Meanwhile, Asymco (http://www.asymco.com)analyst Horace Dediu predicted that Apple’s current-generation iPhone 4 smartphone handset will likely sell around 60-65 million units in total. Sales of its future successor, the iPhone 5, could nearly double that amount, he said.

Dediu based his predictions on Apple’s historical iPhone sales figures, iPhone production ramps and market growth patterns. Through the first four generations of the iPhone, he said, each new version of the groundbreaking device sells roughly twice as many units as the last.
