Displays a warning before allowing the system to load a PDF, to try to help users avoid being duped by malicious PDFs. Please note that attackers may use more advanced methods, such as being at a public wifi hotspot and spoofing jialbreakme.com, so this is not a complete solution to be "safe" from the exploit, but it is moreso a quick hack until a proper patch for the exploit is released by comex or Apple.
As noted to me by iPhone hacker "MuscleNerd", this should not be regarded as a "secure" solution. So I reiterate, this is simply a hack for the time being to give you more control instead of putting you at a needless risk.
This will not install any icons.
