If you purchased your BlackBerry KEY2 or BlackBerry KEY2 LE from Rogers, you'll want to be on the lookout this week for the November security update. Per Rogers software update schedule, both devices are scheduled to be updated starting November 27.
If history is any indicator, once one Canadian carrier begins their rollout, the others are not far behind so even if you're not a Rogers customer, you'll likely want to check for updates around the same time. You can check current updates available for your device variant right here.
