You have to download the pwnage tool and create a custom IPSW for it.. PwnageTool 3.1.4 for iPhone OS 3.1.2 now available

Search Search Search please there are threads with links on how to Jailbreak to 3.1.2 I've also copied those links to a few other threads asking the same question you just did. So the links are in threads here probably without searching if you go through a couple of threads you'll find the links. If you used purplra1n I'm guessing you're on Windows. If you use blackra1n as far as I understand you have to upgrade to 3.1.2 before you can JB which means you'll lose the ability to unlock. So the only way currently to retain unlock is if you get a custom ipsw from a friend with a Mac. If I was wrong and you have a Mac then Tramain has already provided you a link.
