iPhone's arent designed for secure communication (Score 1)

The iPhones encryption is weak. The ability to pull a copy of the whole file system in DFU mode via USB is also sad from a security standpoint. iPhone's offer no native pgp support. Security restrictions are not pushed securely to the device as in the case of blackberry + bes. So if u desire security take a look at the blackberry that succeeds in many of the ways that the iPhone fails when it comes to security. I use iPhone myself, but have used blackberries in the fast and via BES they can actually be locked down pretty well. Also to those who say its just a phone, what difference does it make, phones now store emails, photos, and all sorts of other information. I use my email for slightly sensitive stuff all the time, if my phone got compromised I wouldn't want to have to worry bout a bank account number or ss number being compromised. I really would prefer that my mail be stored in a secure environment. So as one person said, if u really need to keep secret something your doing on your iPhone, setup your own mail server with https access for a web mail that works well on iPhone, and conduct your shady business through that so that nothing actually stored on the device.
