The BlackBerry 8310 is packed with incredible features, including a camera, a multi-media player, built-in GPS, expandable memory, Voice Dialling, BlackBerry® Maps and trackball navigation. Plus, you get all the core functionality you’ve come to expect in a BlackBerry smartphone—email and text messaging, instant messaging, web browser and advanced phone functionality.

Anyone who's busy will appreciate the convenience of the full-screen internet browser, built-in instant messaging and a versatile organiser that'll synchronise with your PC - but the BlackBerry 8310 isn't just about work, work, work. On the back is a 2 megapixel camera with flash, while inside is 64MB of expandable memory and a media player for music and videos.

Email has always been an essential part of BlackBerry devices. The BlackBerry 8310 is no exception, with a full QWERTY keyboard on the front making messages easy. You can control up to ten different personal and work email accounts, complete with message attachments. And that handy keyboard can be used for composing texts and picture messages as well.

The whole thing is wrapped up in a stylishly slim yet curvaceous design (which explains the 'Curve' name) with an intuitive 'trackball' to navigate through the handset's menu, plus quad-band technology and stereo Bluetooth connectivity to help you stay in touch wherever you are... and whatever you are doing.

(Normally £100 per year subscription). Upgrades available include UK Safety camera alerts (£2.99 per month), or European Maps (£4.99 per month) or North American Maps (£4.99 per month).
