Not only has the Pre decided to drop the last day of mutliple-day events, but today, it decided to add duplicates! That's right, I'm going to work twice each day from now on. Woo hoo; I hope my employer pays me twice
And it's not sync'ing certain events and calendars, either.
I've never complained about cool features that are missing from the Pre's calendar app, but when it can't even get synergy straight...it's useless!
