I was looking around the forums and couldn't find what to do, but I have an iphone 3g on 3.1.3 and tried using redsn0w to jailbreak to ios 4.0, but during the downloading jailbreak data part the iphone would restart without cydia installed. I was looking around and was wondering whether I needed to upgrade to a stock version of 4.01 then jailbreak to 4.01 from that point. Thank you for your responses.
 
Redsn0w does not upgrade firmware. You can either upgrade to 4.0.1 and then jailbreak with redsn0w, or create/obtain a custom 4.0 firmware made with PwnageTool and upgrade directly to a jailbroken 4.0.
 
Thank you for the response, but I don't think that I can create a custom 4.0 ipsw for the 3g only the 3gs. If I upgrade the 3g to 4.0.1 using stock firmware then can I jailbreak to 4.0.1 because I don't know if the current version of redsn0w supports 4.0.1. I'm trying to unlock the 3g to sell it for a iphone 4. thank you for your responses
