I tried this The Simpsons Tapped Out unlimited Donuts trick 2 days ago and I received free Donuts to my The Simpsons Tapped Out account in 1 day after I had used that The Simpsons Tapped Out private server.
I personally did it with iOS phone but there are other options like Android. So I think it works for iOS and Android.
It took about 5 minutes to follow all steps which The Simpsons Tapped Out unlimited Donuts trick has. So no much time.
