The T-Mobile Sidekick 3 added much needed improvements, including Bluetooth, a 1.3-megapixel camera, and a miniSD card slot. This also introduced the roller ball scroll, similar to the one on the BlackBerry Pearl.
It seems that someone finally woke T-Mobile and Danger up to the fact that most of the people who bought Sidekicks were teenagers when they introduced the T-Mobile Sidekick iD. This was the company's first go at a young cash-strapped crowd, as the iD was designed to be budget-friendly, plus it had interchangeable bumpers for added customization. However, they missed out on one big feature that most kids want these days: a camera.
No, you're not experiencing deja vu. T-Mobile decided to revamp its Sidekick line by calling this theT-Mobile Sidekick--not the Sidekick 5 or the Sidekick 6--but the one true Sidekick. This was a nice sweet spot for the Sidekick brand, as it finally got a 2-megapixel camera bump along with an overall sleeker aesthetic for its youngster demographic.
The T-Mobile Sidekick LX was probably the best Sidekick yet. The design was nice and sleek, and the interface was made simpler and more aesthetically pleasing. Danger also threw in a bunch of new features like 3G, GPS, a Web browser with Flash Lite support, and even some social network support with Twitter and Facebook integration.
