I've been trying to jailbreak my iPhone 3G using redsn0w for the past two days and have had no luck. Can someone PLEASE give me a step-by-step guide on what I need to do. This is my information so far:
iPhone 3G using 4.2.1 OS and NOT jailbroken at the moment.
I don't care if it's Greenpoison, Redsnow, Quickpwn or any of them (I used Quickpwn in the past), some please help. I tried reds0w's 4.2.1 jailbreak and once it starts up, it says ipsw couldn't be found.
Any help would be great. Thanks.
