It’s unclear whether AT&T and HTC are intentionally supporting the HTC One with the bootloader unlock tool, which means this might just be a temporary hole that AT&T very well could have patched up either by the time the device comes out or shortly afterward.
We’ll be reaching out to both parties to see if this is something all users can look forward to by the end of the week, but it’s wise not to get too excited or bummed either way. For now, just sit back and know that at least one developer has an open device (which we hope will lead to beautiful things in due time).
