I'm not entirely sure how exactly 2G phones work, but I'm fairly certain that upgrading to 3.1.2 factory will re-lock and un-jailbreak your phone. However, you can re-unlock it using pwnage tool (or finding a custom IPSW on a bittorrent tracker - I just looked but there was surprisingly little. You'd be looking for something like iPhone Custom Restore 3.1.2 iPhone 1,1).
Hope that helps.
