What Hacker News says?

  5. > “A device capable of installing unverified software with an increased potential to introduce security vulnerabilities into the OS” is another. The jailbreak community is usually quick in introducing patches for security vulnerabilities. The most recent Mail bug [1] had a patch released 29 days ago [2].
