Most popular mobile phones in current market - Sidekick LX 2009

This 3G incarnation of the Sidekick includes improved support for social networking applications. T-Mobile’s Sidekicks have been cult favorites stretching all the way back to the original grayscale model when it launched nearly seven years ago. Though the unusual form factor with the addictive spring-loaded pivoting swivel has largely prevented it from attracting a mainstream audience, the countless teens and twenty-something who’ve latched on to the Hip top ecosystem have cited many of the same reasons for loving it since day one: an easy, foolproof UI, push email, high-quality customizability, decent web browsing capabilities, and a stellar messaging-optimized layout.
