Also, read the fine print. 5 is the minimum to be eligible... 5 doesn't guarantee you'll get a free psp. However, the more people you refer, the better your chances.
It's the same as the free ipod scam a few months back. Yeah, they give a few away, as a way of saying "thanks for harvesting all these legit email addresses for us", but definitely not everyone that gets 5 people signed up receives the ipod (or in this case, psp)
