Put tea bags in a heatproof pitcher.

In a saucepan bring water just to a boil and pour over tea bags. Steep tea 5 minutes and remove tea bags. Cool tea and chill, covered, until cold, about 1 hour.

Stir in simple syrup, to taste. Squeeze orange and lime wedges into tea and add wedges. Serve tea in tall glasses. Garnish with frozen raspberries.

To prepare the simple syrup:

Add sugar and water to a microwave safe bowl. Microwave for 1 minute; stir until sugar is completely dissolved. Let syrup cool.
