From Profy:
And here comes the competition itself. It is actually as simple as guest blogging – something many bloggers often do absolutely for free without expecting any reward but additional exposure. So simply write a guest post about Web 2.0 (news, commentary, tips, ranting about your personal Web 2.0 experience, etc.) for Profy and send it to iphone@profy.com. If your post is found Profy-worthy and is qualified for the competition, we will let you know when the post is published. So you are in the competition!
Head over to Profy and enter the contest. Why? Cuz we all want an iPhone.
