I wanted to discourage you from doing so until we offer this as an automatic upgrade over Wifi or the Desktop application. Installing the upgrade as a sideload could cause your device to stop working. We will have an official post when 2.1.X is available for everyone.
If you already have received 2.1.1 on your Kobo Touch device through the Desktop or over Wifi this is intentional and this build is safe for you to use on your device.
