Today, HTC announced that its bootloader unlocking tool would now support the HTC Incredible, ChaCha, the Desire Z, T-Mobile G2, Status and Aria. Of course to be fair, the ChaCha and Status are essentially the same phone, just international and AT&T variants, and the same goes for the Desire Z and T-Mobile G2. What's odd is that the Status was actually announced as part of a list of devices added to the tool last week.
Still, an unlocked bootloader is just that, so if you want, those devices are all covered now.
