Open settings, go to general, and tap date & time. Change the date to
2008 (two years before whatever year you're in), and then open your 
virtual families app. Play with them for a while, about 5 minutes, and
then open settings again and change the time back. When you open up 
your app... Yay! You'll have at least 100,000 dollars! There will be 
lots of trash around the house but you can just clean that up.
