paybyphone

I'd be willing to buy ZP if it's possible to buy them through my cell phone. Atleast $10 worth. My pre-paid cell phone has to be loaded $20 a month, and barely is it used, so at times there would be just too much on it. So it would be nice to add a cell phone option to buy ZP. I'd be willing to support the game but this would be the only way I can help.
