Send free/anonymous txt on iPhone?

[Xee]

Hi I want to send an anonymous txt from my iPhone, can anyone recommend a way that will not use my O2 number to send the txt? Its for UK only. Was looking for an app - but there are so many I was hoping for a recommendation. Or some other way of doing it.

Well the only thing that I have found is SMSVeil and that's only on the US iTunes store.
