Yes, there's a new unlock method posted on one of the famous Russian forums. I haven't tried it, but it involves booting once with a rooted boot image, using root and a root adb terminal to overwrite the bootloader with an unlockable one, unlocking the bootloader, and copying the original boot loader back. It seems fairly straightforward, though, as I said, I've not tried it.
