If you want to download the old version, you can click here:
Send unc0ver's ipa to AltStore

If the phone is restarted, or the phone fails to connect to the Internet for 7 consecutive days to automatically update the signature, the jailbreak will become invalid.
At this time, you need to re-jailbreak.
