While the HTC-built G1 has undoubtedly become the face of T-Mobile, the long-standing Sidekick line is getting a new face of its own today. T-Mobile USA has just launched the Sidekick LX, which features a long-awaited 3G radio and the same iconic swivel design that has made the form factor so appealing over the years.Additionally, prospective buyers can look forward to GPS-enabled Live Search and improved video capabilities, and it is available for pre-order starting today in two new colors — orchid and carbon.
