Frame rate on iPad simulator

Hi, I noticed that when i run my app on the iPad simulator it runs at 30 frames per second instead of 60 like the iPhone. I just wanted to make sure that when running on a device it will run at 60 on the iPad as well. Also is there any problems with games running at 60fps on older devices like iPod touch 2g, 3g, iPad 1? My game is very simple but needs to run at 60 fps or very close to it for some timing related things.
