You don’t want your phone to be an open platform,” meaning that anyone can write applications for it and potentially gum up the provider's network, says Jobs. “You need it to work when you need it to work. Cingular doesn’t want to see their West Coast network go down because some application messed up.”

Here's the problem, Steve: keeping the system closed won't stop that from happening -- in fact, it makes it more likely. It's a dead certainty that the iPhone will be cracked, will be turned into a defacto open platform, whether through taking advantage of system or application flaws -- as was done with the just-as-"closed" Playstation Portable -- or through simply turning it into a Linux box -- as has been done with the original iPod. A security plan cannot be based on the concept that nobody will do the obvious.

Once the iPhone was cracked open, people who would have been inclined to use it to do nasty things to the Cingular network (or other users on that network) would still be able to do so -- and regular users would have no tools at their disposal to counter or circumvent that threat, other than those from Apple and Cingular. Which one takes the blame (and possible lawsuits)? That's a situation that's absolutely ripe with the possibility of finger-pointing, instead of solutions.

At the same time, the potential for accidental damage to the network is greater in this scenario, as non-malicious hardware hackers and garage programmers poke around, trying to figure out what the different components and programming interfaces do. A home-brewed application that should be just fine might in fact be disastrous, simply because of a hidden undocumented feature. Realistically, while the chances of this happening are pretty slim, they're still greater than if the iPhone was open to developers, with officially documented interfaces and commands.

In short, a closed iPhone will be no less subject to malice, and probably more subject to accident, than an open iPhone.

The iPhone is still six months away, so there's still time for policies and technologies to change. Given the way Jobs talks in interviews in both Newsweek and the New York Times, however, he may be digging in his heels on the matter, holding his position even when it's no longer tenable. In that case, Apple may be in for a painful lesson in the dynamics of the new world.
