There's already a way to root the Samsung galaxy s4. Thanks to a member from the XDA forum and despite the obstacles set by Samsung, the S4 can be rooted easily with a few clicks. By completing this, you'll be able to get rid of the TouchWiz applications,overclock your phone( srsly??0_o),download applications that require root permissions and much more.... This is how it's done:

Warning

The root entails many risks and if you don't perform the procedure correctly, you could find yourself with an unusable phone. That being said, this method won't have the consequence of loss of data, but caution is advised! Save all of your files beforehand. Neither ANDROID WORLD nor I will be held responsible for any damages incurred on your phone.

It should also be signaled that Samsung's warranty might be nul and void after doing this. If something were to go wrong during the procedure (you unplug the chord accidentally, for example), there aren't any custom ROMs at the moment, though they should start appearing in the next few days. In conclusion, be very careful and follow all of the instructions.
