How to keep my samsung blackjack 2 from hopping on the internet?

I keep having to pay extra on my phone bill each month because my Samsung Blackjack 2 hops on the internet anytime one of the buttons is accidentally pushed. Even if I'm texting and accidentally push one of the buttons I get charged extra. Aside from mutilating my phone by cutting off those 3 annoyingly sensitive buttons that connect you to the internet unawares, how can I keep it from accessing the internet (i.e., leaving it in my purse and having the internet come on all night ugh!). I had a Blackjack 1 and I was able to easily and permanently disconnect the internet in the Wireless Manager. I tried doing this with my Blackjack 2 but it still just keeps coming on at the very gentle press of a button.
