Another great way to speed up any Android phone is by installing a supercharger script.
I recently installed a supercharger script and I must say, in combination with a small overclock, it made enourmous changes! My three-year old phone which is running a pretty new version of Android with the use of custom roms has become faster and snappier than ever before!
