Thank you, i think for now i don't need to jailbreak, maybe the only thing i miss is the GPS Toggle and Wifi (24/24h off)
And i'm afraid of being stuck with an iOS without SHSH, now i can update to 12.1.2 and save the SHSH ? And if maybe iOS 13 or iOS 14 make my phone unusable (stutter, lag etc..) i could downgrade only with the SHSH ?
