Surpisingly or amusingly, after my post yesterday, having decided to sideload the 2.1.4 update, come what may, my Kobo touch updated itself by wifi to 2.1.5 !!!
All I can suggest to those (particularly Australians apparently) who are stuck on version 2.0.0 of the firmware, is to threaten to sideload on this forum!
They may suddenly get lucky!
