disable sms icon?

hi all
pretty new user here
quick question , i downloaded crunch sms from the app world and now i get 2 icons on the home screen every time i get an sms , is there anyway i can disable the message icon from the inbuild sms app , basically i only want to use crunch but at the moment i have to open both apps to see the same mesasge so i can remove it from the home screen ?
any ideas

thanks so much:)

From the CrunchSMS directions: Options / Security Options / Firewall, and check the box next to SMS (leave the firewall off, just check the box). SMS will still come through to SMS for whatever reason, but not to your messages or SMS folders.

ok have tried that hopefully it works
thanks so much for your help:)

Good luck!
