Hey guys, Quick question, I was trying to search on this but didn't find a straight answer. I upgraded to 4.1 on my 3G since the speed on 4.01 was unbearable. Now I know that upgraded the baseband as well. Now I'm JB'd on 4.1 thanks to redsn0w, but with the new baseband so i cannot unlock. I remember saving my SHSH file(s) on Cydia when prompted before I upgraded to 4.1. I heard if you did this you can 'roll back' to your previous baseband. 1)Is this true? If so where do I find a tutorial on it... 2) IF true does this mean I also have to roll back to 4.0x? or can i keep 4.1 AND get my old baseband back so i can unlock. Thanks Edit: when i go into cydia now I see "SHSH: iOS 4.0, 4.0.1, 4.0.2" on top, are those the SHSH files saved for my device?
