From what I remember it only worked with the PSP or Ipod freebies.
Not so sure it works for cameras.
It doesn't work for me with a recently (less than 2 weeks ago) delivered FreePay Nano.
That's what I was thinking, it may be a new zip code. When I get my camera I'll check the zip code and see if it matches up.
Just call DHL and give them your address. They will give you the tracking for the package. Thats the new "trick"
