Sony Ericsson is creating the longest online wave ever and is offering its fans a great opportunity to join two other competitions on the brand’s Facebook page to win specific prizes.

The competitions are the latest in a line of highly successful fan activities run on the Sony Ericsson Facebook page following hot on the heels of South African Wave competition, which encourages contestants to submit videos of themselves waving for a chance to add a replica of the official matchball of the FIFA World Cup to their sport collection. The more people from your country joined the wave, the higher your chance is to get the grand prize.

Fans of Sony Ericsson’s social media pages can also win either a brand new Xperia™ X10 phone, or an Official FIFA World Cup replica football by answering simple questions. The first one is “How many goals must a player score for a hat trick?”—to get the ball Facebookers are just to choose one correct answer out of 3 in the box. To crack the second question—“Which Xperia™ X10 feature allows you to update Twitter and Facebook at the click of a button?”—they are to be real experts in Xperia X10 phones (which comes as a prize), because the brand hasn’t provided any hints. If you want to get this phone, prove you know it.
