How do I change the right soft key on the Samsung Gravity 2?

I just got the Samsung Gravity 2 from T-Mobile. I was wondering if it was possible to customize the right soft key. It currently displays the "web 2 go" shortcut and I don't want to accidentally hit it and get charged. Anyone know how to customize the soft key?|||Unfortunately for this phone, it is not possible to customize this key. But just so you know, if you click on that button, it won't charge you anything. You'll have to sign up for it.
