Wow.
I'm not siding with Apple on the issue given known considerations, but that dude is off the rocker switch. "Dormant cyber pathogen"?
It's not impossible, especially if the phone were jailbroken beforehand, but the chances of that-- why bother when the phone can do most things with a simple flick of a finger?
I don't recall anything saying the phone was or was not jailbroken. Just Apple's own algorithm, for which the "human rights but only when we profit by them because we still profiteer from child and slave labor" advocates start to mewl and whinny.
It's far more likely that documentation for crimes, addresses of cohorts, et cetera, are on that phone and nothing more.
Plus, depending on type of malware, it's not going to get very far. And it's not often when malware made for one brand of phone can magically jump platforms, unless there's a write-once-run-anywhere middleman like Flash or Java and APIs therein to exploit. Jobs was hyperfocused on battery life, no touch capabilities, and resource usage when screaming at the masses (while quaintly ignoring all the battery draining nonsense in the Apple app store), but for the security aspect there was a point, even if he didn't say it*. A convenient one, but one nonetheless.
If nothing else, maybe there's just a recipe for meatloaf and the whole rigmarole circus will have been for nothing - which is not to say other cases would be identical by default...
* At all, or anywhere near as loudly as his other checklist o' attack vectors to wipe out the competition that provided the same games for free instead of $3.99

, I'd read some articles from 2010,
like this one, when he made his claim.
