unwiredbuyer.com has all the details...
It's kind of a neat concept...it's a sniping service working in conjunction with Ebay.
You enter your info and they call you when the auction has 3 minutes remaining. You then place a bid on an item using your cell phone.
I had an item I wanted to bid on anyway (I didn't win, I got outsniped

) but I still got the free $20 US in my paypal account.
There is a referal system, so IM me if you want a link. It is not necessary to use the referal to get the free $20, but it is a nice thing to do
