Speed Intensifier in Cydia is amazing. When loading such things as from homescreen to Safari is fast as light. Its combined with overclocking and animation speeds with adjustable settings in the settings section. My 3GS is so damn fast now loading. Below is a copy and paste from xsellize. This is now my most favorite app to date. By the way prior to trying this I tried IOverclock which is also in Cydia which sucks compared to this.
