MY ONLY PROBLEM IS MASS MESSAGING

I have downloaded many apps to be able to send group SMS but is there a way that i can hack the phone to overide the group limit of 40! I get an error saying that im sending too many msgs at one time! Is there a way i can avoid this! And I cant send group SMS in Handcent. the closest i came was chomp! i send 400 daily txt msgs to 400 ppl and i was on every other network and it worked not i switch to Sprint and get the Hero! WILL A HACK FIX THIS PROBLEM IF SO HOW!
