1. uh, it means that you can unlock your bootloader
2. the best way of relocking the bootloader is restoring a ta backup made before ever unlocking your bootloader (to do that you must be rooted, and to root without unlocking you need to have android 4.0.x, there's a more detailed guide on the forums). it's all academic anyway - there's a way to get back the features you normally lose after unlocking and relocking without a backup, while all problems are software (can be fixed at home) or hardware (in which case bootloader status can't be reasonably blamed as a cause or aggravating factor except for damage by gross overclocking)
