With Apple set to unveil its newest iPhones, a key question for the California tech giant is whether it can recapture the magic from its first release a decade ago. The keenly anticipated media event on September 12 will be the first in the Steve Jobs Theater at Apple's new "spaceship" campus in Silicon Valley, evoking the memory of the company's late co-founder and iconic pitchman. Jobs introduced the first iPhone on January 9, 2007 and set the stage for mobile computing -- and an entire industry revolving around it. The first devices became an instant hit as they went on sale on June 29 of that year.
