Hi! I've had an iPhone 3G for quite some time, and remember jailbreaking it once, through the jailbreakme website. I then thought the device got slower so I restored it and never jailbroke it again. I'm quite a noob at this, so sorry for the silly questions. I've read iPhone 3G run better at iOS 3.x than 4.x. Can I downgrade my iOS 4.2.1? If so, could someone please direct me to a tutorial? Now I'm really sory for this one, I know I'll make someone angry but I have to ask (I just found so many info on the web I don't know in which way to go): What's the best method for jailbreaking my Iphone 3G on 4.2.1? Could someone please direct me to a tutorial? I expected to find stickies with these guides, really! Thanks in advance.
