Started playing on my iPhone 3GS when it first came out in March 2012. Only problem I ever encountered was that I couldn't log. Into my town for a few days in June 2012. Mind you, this was when the game was ou available to a certain amount of people playing because the app was only available for a few days before it was pulled from the App Store. It wasn't brought back until August 2012.
Started playing on an iPad 3 when I bought it in September 2012. No issues ever even til this day.
When they rolled out the Christmas 2012 event, they stopped supporting older devices (including my iPhone 3GS). So I could only play on my iPad.
Bought an iPhone 5 in February 2013 and have been using both my iPhone & iPad without any issues ever since.
