We may not be the sunniest country in the world, but we sure know how to make the most of summer. To help make this year's an unforgettable one, the Guardian, in association with BlackBerry®, is offering one reader and a friend tickets to Bestival, the award-winning four-day live music extravaganza on the Isle of Wight, as well as a BlackBerry smartphone, so you can call, text and tweet your friends to tell them all about it.

Bestival will close the UK summer festival season with one of the finest lineups in its nine-year history including sets from the legendary Stevie Wonder, New Order, The xx, Sigur Rós, Friendly Fires, Orbital, Frank Ocean, Hot Chip, 2manydjs, Florence + the Machine, Miike Snow and up-and-coming New York rapper Azealia Banks.

In addition to stellar entertainment and thousands of fancy-dressed revellers, Bestival boasts a number of truly unique spaces including a boutique campsite, a Bollywood cocktail bar, the Grand Palace of Entertainment, a roller disco – even an inflatable church.

Bestival runs from 6-9 September. Tickets include camping access and entry for all four days. For more information about the festival visit bestival.net.

The lucky winner will be able to capture and share their Bestival experience on their new Blackberry smartphone.

The BlackBerry Curve 9320's keyboard makes messaging quick and effortless. 3G technology, combined with the most powerful BlackBerry Browser yet, means easy access to BlackBerry messenger, email, the web and all your social networks. You can even turn your handset into a Wi-Fi hotspot with up to five other devices.

Music fans will love BBM Music, an app exclusive to BlackBerry, which lets you access millions of songs, create playlists, and swap tracks with your friends. The smartphone also connects to your games console, HDTV or PC.

With a powerful battery to keep you going all day, the BlackBerry Curve 9320 is always ready when you need it.
