Post beta 4, the ramdisk hack stopped working. Sorry Zibri, guess you’ll have to steal another exploit.
Apple doesn’t appear to upgrade the bootloader on phones in the field, probably for fear of breaks. So any old iPhones out there today, regardless of version, can be unlocked.
The iPhone 3G uses a different bootloader, which I believe there aren’t any known exploits in yet. So no unlock."
