In what respect?

Best of luck getting a reasonable response on that.

It'll be very Interesting to read his/her opinion.

Consider your pwn physical security as well as your organization's policies in place.

In terms of security, your device is going to reasonably insecure because of SIGINT requirements. Your organization may, for instance, allow use of personal portable devices but mine doesn't and it is a strictly enforced policy. It is because all cellular signals are subject to interception and interference, and iPhones are no exception to that policy. The only exception that exists in my work is if I had a government issued device such as USB or cell phone that was compliant with DoD standards and has been validated by a supervisor. It's not that I am not trusting of devices themselves, but rather the people that are in charge of creating those devices, and their default settings that are enabled (or disabled), which facilitate interception and aggregation of my personal information as soon as it is available on the device.

That said, you should also take into account the operating system, which is also very insecure by design, at best - e.g., using no method for encryption at rest or FDE unless expressly setup by you or the issuer. All cellular devices facilitate spying because of the ease of use when considering portable malware tools, eavesdropping technology and personal information that most people make available on them.

It's just an unfortunate fact: we routinely use these devices and choose between security and convenience.
