This works 100% on the most recent for the iPod touch 4g update (well for me). I am not sure about any other systems, but it is definately worth a try. Firstly, get as many sims as you can into one house, putting the rest into hibernation. Now, have your awake sims plant your most expensive plant. Click the home button and go to the settings. Find 'date and time' and change the year two years back. Next, click the home button two times, quickly, and then hold your finger onto sims until it is in edit mode. Delete sims by pressing the minus in the games corner (you might as well delete any other games in there while you're at it. It won't mess anything up, besides you're iPod could break if this section gets too cramped. My brother would know.). After that, change the month to one before now. So, if it were January 2nd, 2013, your new time would be Febuary 2nd, 2011. Now go onto sims and wait for it to load. When it is done go back to settings and change the time back to normal. Finally, go onto sims one last time. All your plants will be finished, you will be given a bonus 15,000 simoleans, and all you're people will be inspired. This may seem like a long process, but it is actually extremely easy. Also, once you raise a ton of money you can buy more expensive items for leveling up your town's worth. For each time you level up, you will be awarded five lifestyle points. This is a good way to easily gain 500,000 simoleans in about an hour or two. If your sims do not get the money or are still gardening afterwards press home then come right back onto the game. If it still isn't working you probably did the cheat wrong. I hoped this helped!
