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 ?
Ok, i did the update to 12.1.1 not 12.1.2. Because i was afraid of the issue with wifi/cellular . And finally i had a problem with sharing 4G with USB!! Now it's OK, i hope it will be good, i saved my shsh/blobs in case for future update!
