If somebody would help me with this I sure would appreciate it. I've been trying to Jailbreak my iPhone 3GS for the past week, countless times. I'm using the latest Redsn0w and 5.0...It jailbreaks but when I go back to boot it tethered I get an error and it says unrecognizable build with a Fingerprint. I have the White Cydia icon but It just won't boot tethered!!! I also downloaded Forecast and it tells me NO jailbreak available..Any way around this..Somebody please help!
