Havent seen much discussion of
rewardbull here and thought i would give it a mention.
It is in my opinion, one of the best free ipod sites out there right now, the customer service in incredibly good (espesialy after dealing with freepay and some of the other big networks.) The other thing that sets it apart is that points can be earned either by refering others or completing offers yourself, or with a combination of the 2. Also the site can be done as many times as you wish.
