As a result, he has decided to publish the details of the iPhone vulnerabilities on his own. The first is based on the manner in which the iPhone truncates URLs; because the iPhone has such a small display, it is necessary to display only part of a URL for many given links. The section being cut off can be critical to determining legitimacy, however, and so it is possible to create plausible URLs which nevertheless take people to dangerous websites. URLs can be examined in Safari, but the OS makes this difficult by jumping to the end of an address.

A problem unique to Mail stems from image attachments. Because there is no option to disable downloading attachments automatically, images can be used to gauge whether an e-mail address is active; once this is verified, a spammer can use the information to direct more messages at a target. Raff comments that both this and the URL bug should be easy to fix, which leads him to wonder why Apple has not done anything sooner.
