Just reada following article over at FT.com where the editor had the chance to preview a few select iPhone games.  During their previews, they were able to check out the expansion packs for The Sims 3 on iPhone.  If your phone is up-to-date with the 3.0 OS, then you’ll be able to download these to expand your game.  The first few sets we will see are:  Vampires & Werewolves, Campus Life Wear It Set and the Castle Wear It Set.  Pricing is yet to be determined but we should know more shortly as they’ll start appearing in the iTunes store sometime in the next few weeks.
