Canadian carrier Rogers started its OTA rollout for the One X earlier this month, and now Telus has started pushing it as well. Stated on the official HTC Canada twitter account, the update should start coming OTA (Over The Air) to users as of last night. It will be pushed automatically, but eager users can always check in manually and should have the update waiting at that point as well. These big updates tend to roll out in groups or phases, but usually don't take long to hit everyone.
One user in our forums, guyfrombc, has the update downloading on their device, so we know it's out there in the wild at least in some capacity. Are you seeing it on your own Telus One X yet? Head to the forums and let others know what your experience is.
