Gee I hope not. Nothing more annoying than to have pop-ups reminding me that it's so-and-so's birthday when I really don't care. No matter how many times I deselect the calendar sync on my BB, it still dumps that crap into my calendar.
Yea i actually found this useful on the droid. Helped to prevent me from forgetting birthdays since im bad about that type of thing. Haven't noticed that on my dx yet.
