Safestrap has been working great on my MAXX HD. I haven't taken the update as I've been running a few different ROMs using Safestrap. I try to avoid jumping on an update as soon as it's released as I prefer to stick with the ROM that's been working best for my phone. Eventually a ROM will be released which contains the update anyways. Having the Moto bootloader unlocked is the most exciting android news I've heard in ages and hopefully it means the dev community will be coming out with some some great stuff soon!!
