I want to jailbreak and unlock my iphone 3g but not sure what to do. I have fw 2.0.2/baseband 02.08.01. Can I just use the Preserving Baseband guide on the site or do I need to do something before that? Some sites say in order to use yellowsn0w, you have to be on baseband 02.28.00, is this true cuz mine is 02.08.01. I wish I could just update to 2.2 via itunes but 2.2.1 is out now. I'm not sure what steps I need to take in order to have the latest fw 2.2.1 installed and still be able to use yellowsn0w. Any help would be great, thanks.
