Ok I've successfully jail broken an ipad1, did it before I upgraded it since it is the wife's. Now I got my old iPhone 3G with 4.2.1. It should be unlocked in a few days by my carrier, Telekom. I'm trying to jailbreak it through red snow and every time I get into dfu mode, it posts an error. I have the 4.2.1 firmware downloaded so I don't know what I'm doing wrong. Every tutorial I find is from when the jailbreak came out, so I don't know if there were updates for red snow or anything. One thing it does show is its trying to say jail breaking iPhone 4. Any suggestions?
