Most of the free ipod sites out there on the internet are either scams, or they aren't available to people outside the US. There are now some sites available for residents of the UK, Canada, and even Germany.
I'm a Canadian resident and within two weeks I have gotten all the referrals I need to get a free iPod, so I can vouch that it IS possible, just takes a bit of work and dedication. To find out what sites are legit you should check the forums at Anything4Free.com or FreeIpodGuide.com (these guys have been "playing the game" for some time and know which sites will actually deliver the items promised). Some of the better sites which are much easier to complete are as follows :
Free Desktop ComputersFree Ipod NanosFree XBox 360 Free Video iPodsFree FlatScreensFree XBox 360DVD Recorders Free Digital CamerasFree 60GB iPod VideoFree Sony PSPRemember to always read the terms and conditions before signing up for anything, and keep a record of any transactions you make (they make money when people forget to cancel offers after the free trial period). Good luck to everyone getting your free items!
