As more and more reports begin surfacing about spontaneously exploding iPhone smart phones, Apple says it's investigating the problem and claims it has seen only "isolated incidents." The iPhone maker also told the European Commission (EC) that the device doesn't have a design flaw. Instead, "external forces" are causing the sometimes explosive damage.

Apple was forced to look into the events after the EC contacted it in the wake of an incident in France, where an iPhone started hissing and then suddenly exploded, shattering the screen and injuring the owner. Elsewhere in France, a woman's iPhone was found destroyed, with the screen shattered. No one was hurt.

Apple says none of the incidents are its fault and hinted that its very latest iPhone model—the 3GS—doesn't suffer from this problem at all. Not that there's a problem.

"In all cases the glass cracked due to an external force that was applied to the iPhone," an Apple spokesperson said. "There are no confirmed battery-overheating incidents for iPhone 3GS, and the number of reports we are investigating is in the single digits."

Meanwhile, additional tests on three exploding iPhones are underway in the United States. The moral here is simple: If people want to be safe, they should simply use a BlackBerry or other non-exploding smart phone. Looking for explosions? There's an app for that.
