hello
i have an iphone 4s with ios 5.1.1 jailbroken and i want to update it to 6.1 jailed
if i update it by OTA will it delete a data or damage the phone
and will it work in the first place?
thank you
If you want to go to 6.1 "jailed" then just do a DFU restore in iTunes. You will lose everything that's currently on the phone so be sure to synch your purchases and do a backup first.
