As one of the most popular (and therefore most covered) high-tech devices around, any defects with the iPhone are surely going to make headlines. Not surprisingly, though, Apple has not been forthcoming about these issues and has reportedly gone to great lengths to keep them from going public.
You can easily pull up a dozen or so incidents in which exploding iPods or iPhones have been reported around the world, but on a numbers basis we're still talking about a very minor number of devices. The risk factor is probably very low and very conditional – but is it up to Apple to claim these incidents are isolated? What I would really like to see is solid numbers – sourced from a third party – that indicate exactly how many cases of an iPhone exploding there truly have been.
