I was wondering if anyone could help me find a way to make my iPhone 3G repeat the SMS tone, I know it does it 3 times or whatever but I need it to continue repeating until I read it.
Mainly at night as I receive many texts during my sleep that I need it to continue going off to wake me up and other stuff to.

So is there any app/edit or whatever that I can do so my SMS tone will repeat continuously?

It is jail-broken by the way.
