Plantronics is offering the chance for one lucky reader to win a brand new 32GB white iPhone 4 complete with the latest Plantronics Voyager Pro UC Plus worth over £700.

To enter, all you need to do is follow @PlantronicsUK on Twitter and Tweet about the most extreme location you’ve ever made a call from using the #PLTXT hashtag! And if you’re feeling really adventurous - link it to an image or send us a photo and we’ll post it up on our website for everyone to see!

Was it while you were halfway up a mountain, flying through the air on a rollercoaster, traversing the icy conditions of the Arctic, bungee jumping off a cliff or did you suddenly get a call while you were in the middle of a parachute jump? Whatever it was we want to hear about it!

The winner will be announced on the website and contacted via Twitter at the end of August, and two runners up will also receive a Voyager Pro UC Smartset worth £119.

For more information about this competition and how to enter please contact us via the feedback form.

Winners will need to continue to follow Plantronicsuk on Twitter otherwise we will not be able to direct message you to let you know you’ve been selected as the winner at the end of the competition.
