Anyone waking up this morning may find that The Sims FreePlay is now available for the iPhone, iPod Touch and iPad. The minimum requirements are that you need an iPhone 3GS, a 3rd-generation iPod Touch or later in addition to iOS 3.0 or later. The download is 409MB in total, meaning that anyone wishing to download directly to their device must connect to a Wi-Fi network.
Here is the direct link to the game on the iTunes Store.
EDIT: It has been listed as EA's free app as part of their holiday promotion.
