Preheat your oven to 375°F (190°C).
In a large bowl, mix flour, sugar, and salt.
Cut in the cold butter until the mixture resembles coarse crumbs.
Stir in the ice water, a tablespoon at a time, until the dough forms.
Divide the dough in half, shape into discs, and refrigerate for at least 30 minutes.
Roll out one disc and fit it into a pie dish.
Mix the fruit filling with sugar, lemon juice, and cinnamon, and pour into the crust.
Roll out the second disc and place it over the filling; cut slits for steam to escape.
Bake for 45 minutes or until the crust is golden brown.
Cool the pie before slicing and serving.
