Locked vs. Unlocked for OS Updates
I received an AT&T variant of the One M9 directly from HTC. Since it has the AT&T logo on the back and lists AT&T as the carrier in the "About Phone" section of settings menu, I assume that to mean it's "locked".
I noticed that HTC One M8 and M9 unlocked devices will receive Android 6.0 before the AT&T versions. Does this mean that having a carrier variant device unlocked means you'll receive the updates sooner?
I'm really sick of being last in line receiving updates on my phone thanks to AT&T's non-existent efforts in expediting the implementation of their bloatware to work with each new Android update. I think it's unacceptable that Android users have to own unlocked devices in order to receive timely software updates.
