Update: Scratch that, folks! We've just unlocked the Photon Q!
Motorola has finally started their bootloader unlocking program, but it's not yet complete. The process, which Moto promised we'd have in late 2011, looks very similar to the way HTC and ASUS are going about it. You'll register , read through all the warnings telling you not to unlock your bootloader, and use the Android SDK and fastboot to OEM unlock the phone with a key.
We've no problem with this method. Having people familiar with the tools used to do the deed before letting them do something as important -- and dangerous -- as unlocking the bootloader on their phone is a good thing. Like HTC's tool, we're going to assume that this doesn't give you a full unlock, where radios and other proprietary things can be fooled with. We're OK with that too. Files we're not legally allowed to distribute or hack at are off limits, which makes carriers feel better. Besides, it's pretty simple to work around if you just have to have access.
The one little issue here is that no devices are listed as unlockable just yet. You'll find a link to the supported device list, which asks you to sign up then gives you an error page. We're hoping that this is just a work-in-progress sort of thing and the list will get fuller shortly. Of course, this will all be at the carrier's discretion, so there's a good chance your RAZR MAXX won't ever be listed. Like many of you, we'll be keeping a close eye on this one.
