I change my vote. Homesmack is by far the best solution to this issue. Thank you for the recommendation.
This helpful utility gives android users the versatility to assign the single tap action to whichever homescreen application they prefer; alter the functionality of the double tap action to initiate any application on their phone; and for the first time, provides an effortless method for remapping the long search action.
The app-based solution, a utilization of 'Homesmack', not only offers users with more capabilities and customization than any other method suggested in this thread (yes, I know that includes my own), but it does so in manner which conceals all the backend system manipulations, and instead, presents the user with a simple graphical interface to make their selections.
If this description didn't already convince you, Homesmack is available for FREE! The developer should really consider submiting a "donate version" to the market as well; I have a feeling that I'm not the only one who thinks (or will think) this app is helpful.
