I agree with everything posted here. I also try and limit my fruit into to 1 or 2 servings a day, and on days that I over indulge, I make a point to try not to eat as many other carbs for the day.
Berries tend to be the best low carb fruit, though I also eat small portions of apples, oranges, nectarines, etc. (generally a quarter of an apple or orange, or a half a nectarine, makes for a good snack-sized serving.). There are a number of websites that list carb amounts or GI information for various fruits.
Such as this one:

Mango and pineapple are the hardest for me because I love them but they are quite high in carbs/natural sugars.
