iPhone geeks, I need your help and I challenge you on this..

Hello all,

I know this sounds weird, don't @ me But I would like to send an empty text from my iPhone to other numbers!

Is there any way (any app) to do that?
btw, my iPhone is Jailbroken with iOS4 (not 4.0.1)

I need to know this because some numbers (like my carrier) send billing info as a reply upon receiving that empty text.

FYI, when I say "empty text" (or message) I mean without pressing return (Enter) and without adding any spaces, numbers, symbols or characters at all

Thanks for any help!
