Need help to upgrade from 3.0.1 to 4.2
Hey guys, I desperately need help to upgrade, jailbreak and unlock my 3gs to ios 4.2. I am pretty new to iphone. I got mine from a frnd just a week back and noticed that the phone runs on iOS 3.0.1.
The phone was jailbreaked using Redsn0w for 3.0.1, unlocked using Blacksn0w. The bootrom was not updated during the upgrade. The baseband version is 04.26.08.
My frnd says that he has the shsh file saved in cydia. But, I am not able to view the stored file. I will also need help in storing the furrent shsh file in my desktop(if possible)
Thanks a lot in advance
