The Marshmallow update for HTC One M8 and One M9 units on AT&T’s network will start rolling out today. This was announced by the Taiwanese company’s VP of Product Management Mo Versi on Twitter.
HTC One (M8 & M9) AT&T owners! Thank you for your patience. Marshmallow OS is approved, OTA to start tomorrow!!

If you recall, back in April, Versi had revealed a “slight delay” in the roll-out, saying that they expect to receive the approval for the update within a couple of weeks. So, in that context, the update roll out is bang on time.
However, given that fact that three of the Big Four carriers in the US have already rolled out the update to both devices, AT&T is no-doubt late to the party.
