help with messaging button??

[chelsea_fc]

is there a way to disable the message button in the bottom right corner, so when it pressed do nothing?? and i don't want to use 3rd party program like "ae button plus".
i recently install s2u2 and it works great, but it can unlock when the message button pressed. i can mod the ie and camera button but no luck with the massage button.
plz help....

thanks
