I am up and running as well. Activating on BES now
I haven't had much time to play, but before I activated on BES I tried all my apps and they are all fine.
Poynt, Yelp, Google Search, Google Maps, VZ Navigator, Weatherbug, Yankees icon (be kind), ScoreMobile, FreeTips.
AppCenter doesn't work, so no way to check on those apps, but I didn't use them anyway.
FAST and I am starting to love threaded SMS very quickly. And (I know, stupid SMILEYS!)
The only thing I have run into so far is Enterprise Messenger. We use it daily for Sametime and while it shows as installed AND I have deleted and reinstalled, I cannot find the icon for it anywhere.
