My question is... With the iPhone 4 being jailbroken and everyone being able to view the root directory, what exactly is being stored on the iPhone that we wouldn't already know about. Obviously geo-tagging would store location info on pictures and web cache / history needs to be emptied out, but is there a hidden file that captures more data that we just don't know about??? Any input? With HandyLight sneaking through the app store, I bet someone could put malicious code that transmits personal info (location or data from phone). This really should be explored!!! From the front page of FoxNews.com http://www.foxnews.com/scitech/2010/08/07/smart-crooks-dont-use-smartphones/?test=latestnews "There's plenty of information an iPhone hangs onto," Jonathan Zdziarski, author of iPhone Forensics, told FoxNews.com. "For example, the iPhone takes a screen shot every time you hit the home button, including shots of your e-mail with the time stamped on it." Mapping software will store locations you've searched or directions you've received. The auto correcting typing feature of iPhones actually stores words you've typed, which could potentially be accessed months after a message was sent and deleted Do you carefully delete all of that personal data to play it safe? No matter, it still may be accessible to thieves or law enforcement.
