Siri can make interacting with your iOS handset easier, and more specifically, the ‘Hey Siri’ feature comes in handy when you have dirty hands and you don’t want to touch your device. But when your handset is locked, Apple prevents Siri from accessing certain things to protect your privacy from those who may try to exploit her handiness to reveal personal information about you.
While we can understand Apple’s reasoning for doing this, we also understand that some iOS device power users care more about functionality than privacy, and so it would’ve been nice if Apple offered more flexibility in this department. Fortunately, a newly released and free jailbreak tweak called SiriUnlock by iOS developer CokePokes makes this happen.
