iPhone OS 2.x did not support Exchange. So I think you can make a reasonable case that before June 19th 2009 very few of these encryption-required companies were buying iPhones since they simply didn't support Exchange. This is factually incorrect. I've been using the Exchange integration on the iPhone since fall 2008. Granted, as this article shows, Apple has been reporting false information to Exchange, but the Exchange support has been there.
