I had the Iphone4 OSi 4.0.2 (unlocked and jailbroken)
At that time I clicked on the button to save my SHSH file( the other button to "No, Thanks...") on Cydia.
Is it possible to search for this file on my local system... ?
Currently I am at 4.2.1 with baseband 3.10.1 (tethered jailbroken) with no way to unlock my phone.
Do you think searching for the .shsh extension file can solve my problem, if I can downgrade it somehow ?
