Apple's iPhone turns 10, bumpy start forgotten

San Francisco

APPLE Inc's iPhone turns 10 this week, evoking memories of a rocky start for the device that ended up doing most to start the smartphone revolution and stirring interest in where it will go from here.

Apple has sold more than one billion iPhones since June 29, 2007, but the first iPhone, which launched without an App Store and was restricted to the AT&T Inc network, was limited compared to today's version.
