iPhone 3GS w/ios 4 Not Jailbroken
I have purchased a 32GB iPhone. The ipPhone has ios 4.0 and the old bootrom.
This phone has never been jailbroken or unlocked. As I am new to the iPhone
but a long time Apple user, it is my best understanding that this iPhone cannot
yet be jailbroken, as the ios has been upgraded to 4.0? I do not have, nor do I believe the previous owner has the ECID SHSH saved, so I have no way of downgrading the software to 3.1.3. Are there any other options I have to jailbreak the phone or downgrade the software? Will it ever be able to be jailbroken as the iPhone-dev team seems to have turned their attention to the iPhone 4.0.
