I just copied this two days ago from another site and haven't tried it yet. It doesn't have orange jello, but maybe it will help. It was posted by JoAnn Reno Wray.
1 11 oz can mandarin oranges
1 8 oz can crushed pineapple in its own juice
1 14 oz can low-fat, sweetened condensed milk - NOT evaporated
1 12 oz can Five Alive or orange juice concentrate, partially thawed
1 2 liter bottle diet orange soda (orange slice works great)
ice and salt for ice cream maker

in a blender, whirl the mandarin oranges and pineapple until all pieces are small, about 20 to 30 seconds. add the low-fat, sweetened condensed milk and blend briefly until mixed. add the frozen juice concentrate and mix again. (if you need to, mix the fruit first. then mix the condensed milk and juice concentrate after emptying the blender jar into the ice cream maker.) using a large whisk, gently mix the blended ingredients while pouring the orange soda slowly into ice cream maker. pack ice and salt around container. turn the motor on and allow to mix til sherbert is thickened and frozen. place in freezer and allow to freeze further, or serve at once.

recipe can be altered by using different soda, juice and fruit. strawberry soda, strawberry-lemonade concentrate and 2 c fresh or frozen strawberries, or
1 1/2 c strawberries and 1/2 c bananas. or peach soda, lemon lime soda and fresh peaches.

I know that isn't exactly what you asked for, but maybe it will help.
