If your iPhone is already jailbroken using JailbreakMe tool, then you might want to know it will open a security hole as the result. JailBreakMe utilizes a PDF vulnerability in OS and now all people know it including the hackers or other bad guy, so there is chance they will launch malicious attacks to your iOS device via PDF file to gain access to your iPhone restricted area.
Apple has already aware of this problem and will be releasing the fix – but no official report about when it will arrive. Mean time you can protect your iPhone by doing this preventive acts, do not open or download any PDF from untrusted sources and then taking this advice from F-Secure: “Download a jailbreak application named PDF Laoding Warner from Cydia store” Of course changing SSH password is also smart deed to protect your iOS device.
But thanks to JailBreakMe because it we know this vulnerability.
