Here is explained how to control your home with your iPhone.
So turn your light on and off, ...

But it's not well explained (maibe because english isn't my best language)

Does anyone know alternatives to control your lights with your iPhone?
(and with a cheap solution of wireless receivers)

It looks very handy and cool to control your home with your iPhone.

Thanks!
(sorry if my english isn't always correct)
