Apple's invention of the Click Wheel has spawned many imitators, be it in other digital audio players, portable media players, GPS navigation devices, or cellphones. LG's new 3G-capable U400 music phone comes with a scroll wheel that provides easy navigation through the menu system, offering unparalleled control over the MP3 functions. You can pretend to be a DJ by turning the scroll wheel to produce a scratching sound while an MP3 is being played. Other features include video calling, stereo Bluetooth connectivity, a pair of stereo speakers, a 2 megapixel camera, and a microSD memory card slot.
