Prepare syrup: In a small saucepan over medium heat, combine pomegranate juice and sugar, and bring to a boil. Reduce heat to a simmer, and cook for 10 to 15 minutes, or until reduced by half.

Meanwhile, remove frozen dessert from the freezer and let soften for about 10 minutes. Transfer to a bowl; swirl in 2 tablespoons pomegranate syrup and seeds. Return to the freezer for 1 hour.

To serve, slice loaf into 8 slices. Top with a scoop of frozen dessert, and drizzle with remaining pomegranate syrup.
