how to jailbreak iphone?

Bring it to a istore hehehe This always works! I tried to jailbreak a IPAD sometime ago

Wait for unc0ver to be resigned or use taurine,

If this doesnt work use checkra1n, its not untethered though.

Also theres a good possibility that unc0ver isnt expired its just youre on an unsupported device, unc0ver is only for 14.3, chip doesnt matter.

Breaking out of jail might be faster than waiting for a13 14.5+to have a compatible jailbreak

depends upon what version of IOS you are on and if you're on the latest version you are going to have to wait until a jailbreak is available in that version

Newer iOSes are more difficult to jailbreak. If you drop down to 13.8 - 14.1, I hear it's slightly easier. Be careful though, installing rootkits and the like can leave your phone suspectible to attack.

Is it possible to bypass faceid or icloud lock??

a jailbreak is available in that version

Just go to https://unc0ver.dev/ they have explained it there

ipa-apps.me or with altstore maybe
