Two ways to look at that: 1. Apple hasn't had any real competition up to this point. When customers start seeing Google Voice on other phones, the demand will force Apple to rethink their approval policy. Google Voice may not be on the iPhone yet, but saying it will never be on the iPhone is a stretch. 2. Some customers may respond, "Sure, Google Voice is cool...but can your phone do this?", and then have a conversation with you in an auto-tuned voice using an iPhone app (of course, no one would blame you for smacking them...but there is a segment of iPhone users who will stick with the iPhone purely for the apps...) Of course, Android's market share may get to the point where developers will be happy working on two platforms (or shifting primarily to Android and it's range of devices...)
