Those built-in sources are reviewed to ensure they contain no backdoors, malicious plug-ins, or content that infringes users' privacy, rights, or interests. Users must carefully evaluate any third-party source they add or use and assume all resulting risks. Users must also have proper authorization for every app they process. Direct installation on iPhone is available only when an IPA has been signed with a valid certificate and meets Apple installation requirements.
