Be careful.... Replacing the Glo O/S is a COMPLETE HACK that is based on the fact that there is Android device from Germany (
Tolino Shine) with comparable h/w to some of the Kobo eInk based eReaders.
See
Android on Kobo: "Tips and Apps"
and
Android on Glo
Of course Kobo customer support will have ZERO idea about this.
As soon as Android IS installed on the device, it is no longer a Kobo eReader device; all of the functionality supplied out of the box by Kobo is removed.
