It's Sony PlayStation Vita launch day and to celebrate Pocket-lint is offering five lucky readers the chance to win a copy of Codemasters' F1 2011 for the new handheld console.

The game allows you to compete in a full Formula One season, including practice, qualifying and the races themselves across all of the officially licensed tracks. Plus, you can jump into any individual Grand Prix, and there's a Time Trial mode thrown in for good measure.

In addition, the handheld version of the game even features an extensive Challenge mode, which sets a wide range of objectives to perform, including checkpoint, gate and overtaking tasks. And you can even race online against three other people.

To be in with a chance of winning one of the five games on offer, all you have to do is follow us on Twitter (@Pocketlint) and retweet any story on Pocket-lint including the hashtag #plf12011.

The competition will close at midnight this Friday 24 February, after which time we will draw the winners and inform them here and by direct message.

Please ensure that you read Pocket-lint's terms and conditions, and we must point out that this competition in only open to entries from the UK and Ireland.

Good luck.

UPDATE: The competition is closed and the winners, drawn out of the hat from those who qualify are, @frankrobbo555, @andyeaston85, @cobbiecollinge, @PaulNichol and @marclanders. Congratulations to all of you. We'll be contacting you through Twitter's DM to get your details.
