To help promote the upcoming release of their iPhone app, SquareSpace.com has launched a very simple, but effective, campaign using Twitter. They are giving away 30 iPhones in 30 days for simply being mentioned in other people’s tweets.

Using the Twitter “#” grouping feature, they asked people to include “#squarespace” in their tweets. At the end of each work day, Squarespace does a search for that reference hashtag and randomly selects someone to win an iPhone.

I especially like the fact that the prize complements their upcoming app. Check it out.
