I do not have a real world example. However it is because of these issues and many other things that many big businesses will not adopt an iPhone. My company has around 19,000 BBs, (northeast region).
That's nice, but that's also probably more due to technological inertia than security.
Meanwhile, where I work there is a mix of devices: Blackberries, Windows mobile and iPhones. The iPhones are definitely winning out.
Blackberries get lost, I would imagine because our users don't pay for them. If we had subsidized iPhones, they would get lost as well, the user doesn't feel compelled to take care of the device because it does not belong to them.
Generally, when one of our employees loses a device, they have to pay for its replacement, AND the data on it is assumed compromised and they must assume responsibility for that. And they know this before agreeing to it. Regardless of what they choose to get.
Do to the nature of our business, we can't take the risk on the iphone until they implement the security better.
Hogwash. if you really think your Blackberries are giving you added security, you are buying into a myth. Have you ever thought about how your company has no control, at all, of what happens to e-mails and online communications once they leave your server? The greater security breach here is the apparent inability of your company to train your employees not to share sensitive information over insecure e-mail and wireless networks. The Blackberry isn't protecting you against that at all.
Either you are overstating your security needs, or you have a bigger security problem that no mobile device can solve for you. Either way, you are badly misinformed and have bought too much into sales pitches and blog posts.
Bottom line is, at the end of the day, you can possibly secure the physical access to the device better on a blackberry, and there might be dubious arguments that the link between the mobile device and your servers is slightly more secure (though a good VPN connection on an iPhone takes care of that easily). But both issues are the least of your worries.
Let's also look at some the pundit's claims here You cited:
http://www.wired.com/gadgetlab/2009/06/iphonesecurity/
Which states "The remote wipe is useful, but for someone who’s targeting an enterprise phone specifically, that remote wipe can only take place if the iPhone is on a network. If I steal someone’s phone and I have the goal of stealing information on that phone, the first thing I’m going to do is pop the SIM card out."
So.... the SIM card is permanently locked into a Blackberry? When did this happen? And second, I would like for someone to demonstrate a remote wipe from a Blackberry not connected to a network.
A lot of the other links point to people with vague doom-and-gloom "Oh this is easy to hack" statements without any proofs of concept. That doesn't say a whole lot.
