As someone who's been around the block a few times with mobile technology, I get a kick out of lengthy treatises on the practices one should follow to keep the information on your iPhone secure. They follow a commonsense pattern: Use a PIN, set the device to auto-lock after a minimal delay, set it to blank itself after a limited number of invalid unlock attempts, block access to the App Store, use Safari's security defaults, and use WPA2 security for Wi-Fi. This is helpful, but it isn't enough. Users of the iPhone, and mobile devices in general, deserve the big picture regarding the balance of security and convenience.
