One possible reason - what is your internet source? I find when I am on wireless, and close to the router, it runs pretty well - but when there is traffic, or something blocking the signal, it goes pretty slow. I never seem to have a problem when I am on 3G though.
Also depends on the amount of items that person has in their SF - the bigger the city, with the more decorations, the more the game grinds to a halt. I also find tapping a bit slower, and waiting for the game to load helps a bit - just means things take a bit longer, but seem to ease off after a while (playing on an iphone 4)
I'm sorry... I wish I could give advice here but I have the same issue (have been for months actually) the only thing that helps mine at all is removing neighbors with farming towns. But even that's not a cure for the crashing. I'm also on an iPad so any advice from me would be irrelevant. I hope someone can help you... It makes the game frustrating and most of the time unplayable.
