3.1.3 Without SHSH On File?
I have a colleague who wants me to jailbreak his previously un-jailbroken 3GS for him. Luckily it has the older bootrom that is susceptible to jailbreaking.
Unluckily, he allowed it to be upgraded to 3.1.3 by iTunes and the baseband is now at 05.12.01. As it was previously not jailbroken, the ECID SHSH is not on file with Cydia.
I would just like to confirm that, as of right now, this phone is not able to be jailbroken at all. Is that correct? It does not need to be unlocked, just jailbroken.
