The same 'MID ERROR 160' that I have experienced is also happening to units being delivered to customers today, and has apparently has been present on other AT&T devices in the past. This points to the fact that for whatever reason, the AT&T devices are deliberately not unlockable. We have had confirmation that Rogers One X units (essentially the same hardware) do unlock fine, which does lead us to think that this is not an accident!
I've put a call in to my contacts at HTC to work out exactly what's going on but, well, it's looking like seriously bad news! If you've just taken delivery of your shiny new pride and joy, post your thoughts below and i'll make sure they get read by HTC / AT&T.
