iPhone 3.0 mail security
A potential security issue in the iPhone 3.0 firmware has surfaced via a YouTube video. The bug allows users to view previously-deleted e-mails, by searching for the title of a deleted message. The results screen displays two copies of the message; when either is selected for the first time, Mail crashes. When the messages are selected a second time however, an iPhone will either display the original text, or a warning saying "This message cannot be displayed because of the way it is formatted."
The copied message also warns that it is "only partially downloaded," and presents a malfunctioning button to download the remaining part of the e-mail. The bug further displays opened messages in either the Deleted Messages folder or the Inbox as "1 of 0."
The poster of the YouTube video says he suspected the device was reaching back to an e-mail server, but was able to disprove this by emptying his POP account. The bug is believed to be long-standing, as a result of finding e-mails deleted months ago.
