So iOS 4 never got back the speed it had from iOS 3 on my old phone, and I can't buy a new one anytime soon, so I'm figuring that downgrading is the best option to make it smooth again... But Googling says I need "SHSH" files, which I don't have since I've never jailbroken it. However, some answers in these forums seem to indicate that it's still possible, but a lot of abbreviations are getting thrown around. Could someone please tell me the procedure without using abbreviations, so I know what to start reading about? Thank you!
