I have an iPhone 4 here that is currently jailbroken on 4.0.1. No SHSHs have been saved through Cydia so I'm a little hesitant to try and upgrade because I can't go back if something goes wrong.
Is this possible to install a non-current firmware without a saved SHSH? How can I go about getting this thing up to date?
Thank you much!
Adrian
