getting referrals
Start with your friends and family - if you can persuade at least a few of the people you know to have a go, you'll soon be on your way to getting your free iPhone.
After that, try advertising your free iPhone 3G S link on internet bulletin boards, work notice boards, facebook, myspace etc.

general tips
Don't try to cheat the system. You will be caught out and will lose your account.
Be careful not to have more than 1 referral from the same address, or IP address.
An offer only counts if you are a brand new customer.
You can only complete an offer once.
