Just got mail from Vodacom to sign up for approval for the iPhone 4: http://www.vodacomcommunications.co.za/index.php
That looks like a fake site someone created to harvest email addresses... I would NOT enter any details on that form if I were you.
Just have a look at: http://co.za/cgi-bin/whois.sh?Domain=vodacomcommunications&Enter=Enter
It was registered for the first time on the 9th of September this year.
And if you look at the source, it's basically a copy of http://www.vodacom.co.za/iphone4/ with some of the javascript includes commented out.
Anyone know where to report this site so it can be properly investigated by the autorities? I've already sent it to Vodacom to check out.
