The device, manufactured by Danger, debuted in 2002 under the Sidekick brand name and was aimed at a high-spending, high-fashion youth market who were keen on IM and email from their phones.
The Sidekick, sold exclusively by T-Mobile in the UK and US, comes with a slideout screen revealing a full Qwerty keyboard. While the phone hasn't really taken off in the UK, it's a popular choice Stateside, where it's best known for being hacked and spilling Paris Hilton's socialite secrets.
