If you’re an optimist, the more intriguing possibility is that Apple’s iPhone is a Trojan Horse. The iPhone is fatally attractive to AT&T, since it gives the firm a chance to steal tens of thousands of new customers from rivals like Verizon. But Apple may be betting that, once it has its customers, they’ll be more loyal to Apple than AT&T. With its foothold in the wireless world, Apple may be planning to slowly but inexorably demand more room. If iPhone 2.0 is a 3G phone that works with any carrier and supports third-party apps, then industry power will begin to move away from the carrier oligopoly and toward Apple and other Silicon Valley firms. Now, that would be a revolution.
