If you are trying the websites like FreeiPods.com or FreePhotoiPods.com, GearLive is a way for you to trade your referrals. When you register, you can list all of your current open offers. You also list all of the offers that you are eligible for. Then you can search for all of the people who can help you fulfill your offers.
Within an hour of signing up, I got contacted by people who wanted to help me get my referrals and they want me to be one of their referrals.
By the end of the day, I signed up for FreePhotoiPods.com, and got 3 referrals.
If you sign up with one of these offers, send me an email, and I will sign up with one of the offers that you need referrals for.
