In a medium pot, pour the boiling water over the sugar and stir to dissolve. Add the tea bags and steep for 8 to 10 minutes. Remove the tea bags with a slotted spoon. Add the cold water, orange juice, and lemon juice, and stir. Let cool.
Pour into a glass pitcher and refrigerate until well chilled. Pour into glasses filled with ice, garnish with lemon or orange wedges and mint, and serve.
