Kobo has not yet (and may never) weigh in on installing from the .zip file. They did tell people NOT to install the 2.1.1 .zip in a thread all its own.
I know 2 Kobo touch, all from Fnac (So same partner), buyed same time (oct2011) who have the 2.1.4 auto-update in wifi the same day (this morning)... an one is 703 the other is 710.
