Well, I'm happy to report that I myself upgraded to 3.3 and Wi-Fi bug has indeed been solved! Like long forgotten days of 2.x it connects and reconnects without any problems. As for Pocket functionality initially it wouldn't synch any changes from my Pocket account but after signing out of Pocket on Kobo HD and signing back in, it's been synching normally without issues. Plus a major point for me, on 3.3 CoolReader works perfectly well again, not sideways like it was on 3.2.
All in all so far I'm a happy camper, it connects to Wi-Fi, opens books in CoolReader and synchs my Pocket articles and that's all I want from my ebook reader. Hope it works out in your case, such a shame to abandon this beautiful hardware because of a buggy software
