I'm using an iPhone edge using 2.0.0. Recently I've noticed that all the apps have been loading slower than they used to, it takes 6 seconds or longer to load the basic apps like Timer, Notes and Settings. So I'm wondering what app could have caused this slowdown?

I've unchecked the Winterboard themes and widgets and noticed that it now takes 3 seconds for the apps to load. I'm not sure what the default load time is for apps but just in case would there be other apps that could slow down the load time for all apps?
