hi guys iam taking a new iphone 3gs but i have a qstn…
i heard that the latest iphone 3gs is tethered.. n i know wat it is..
all i wanna know is if i use the latest Blackrain jailbreaking and unlocking tool… will the tethered problm be rectified like i cant restart ma phone when ever i feel.. wont have to face the prob in future…
i did everything listed up unil the reboot stage…it won’t reboot, why?
First of all, i would like to thank you for your guide on how to jailbreak my iPhone using Blackra1n.It worked perfectly without any problem.
Now with Apple upgrading it’s iTune, is there a way to jailbreak the new firmware 3.1.3 (7E18) cause i accidentally upgraded it and all the apps that i’ve installed from Cydia is gone.
