For a long time, iOS 9.3.5 was considered unjailbreakable because it patched the exploits used in earlier versions. That changed with the release of Phoenix. Developed by Siguza and tihmstar, Phoenix is a semi-untethered jailbreak specifically designed for 32-bit devices running this specific firmware.
Sideloading: Since you cannot download Cydia directly from the App Store, you use a tool like Sideloadly or AltServer on a computer to "sign" the Phoenix app onto your device using your Apple ID.
