Samsung's just doing what they do best: launching indescribable numbers of rather interesting phones. In this case we have two UMTS phones, the SGH-Z400 and Z550 which are both sporting 2 megapixel cameras, Bluetooth, and microSD memory expandability. They're accompanied by two super-slim EDGE sliders, the shiny SGH-E900 (pictured), which packs a 2 megapixel camera and Bluetooth, and the SGH-D870, which Samsung claims is the world's thinnest slider at 0.51-inches thick. The D870 also bests its peers with a 3.13 megapixel camera, and both of the slim phones include TV-out. All of these units throw in 2-inch QVGA displays and video messaging, and the two 3G handsets appear to include a second VGA camera for video conferencing, but we can't be sure. We should be seeing the phones popping up around the world this year, and maybe if we're good Santa will let us Americans breath on one before the year is up. Click on for the pics.
