This article orignally only noted Bell, SaskTel and TELUS as having released the update. We've seen added Rogers to the headline as they've released it as well. Thanks!
If you're a Bell, SaskTel, Rogers or TELUS customer and been wondering when your January security update would arrive for your BlackBerry KEYone wonder no more. All three have now begun their rollout of build AAT498, which in addition to security enhancements also brings with it the new Files app as well as Locker Mode, something not all carriers have decided to push at the same time.
If you haven't already got the updates downloaded, go ahead and check for updates now and see if they're waiting for you and if they are, get them installed. If you do not see the updates as of yet, hang tight and check back later as carriers like to push them out in phases. As always, if you prefer to wait and see how the updates perform for others, you can swing by the CrackBerry BlackBerry KEYone forums for more discussion.
