Do you have to root it ? and can you please give a step by step guide. eg settings/ applications ect.
Lots of ways:

1. Go to Menu>Settings>Applications>Manage Applications>scroll to the application>open it>uninstall

2. If using default touch wiz, go to app drawer>menu>edit>click on the (-) sign on the upper right corner of the icon.
