Some people—actually a lot of people—don’t much like AT&T. Or they don’t want to pay AT&T’s roaming fees overseas and would rather use a local cellular company. And these people will always be looking for ways to defeat Apple’s locking system. The simple way to defuse this fight, of course, would simply be for Apple to sell an unlocked iPhone for, say, $300 more than the locked version.
But this gets at Apple’s propensity for control. The phone is, in some ways, a better experience on AT&T because of its links to voice mail and so on. But does that mean if Apple’s way is better it should always prevent people from using its products in some less optimal way?....
Apple essentially has two choices. Either it exposes most of the iPhone’s capabilities to developers. Or it will have to gird for an ever escalating war in which it will have to send ever more electronic brick-bombs to its best customers who don’t follow its strict rules.
