LG has unveiled the KM900 Arena, an iPhone-like slab that will hopefully improve on the company's mediocre LG Incite from last year. The KM900 touchscreen handset includes LG's proprietary 3D S-Class User Interface, which features a cube-based layout with four customizable home screens for quick access to music, movies, pictures, and more using three-dimensional menus.

The company's announcement includes a lot of flowery language and little on the way of specifics. But the KM900 appears to include a high-speed HSDPA 7.2 data radio, A-GPS, and Wi-F—three things that are fast-becoming requirements on today's smartphones (at least on AT&T and T-Mobile; Verizon and Sprint use EV-DO-based 3G data radios instead). LG didn't even specify an underlying OS for the thing, though. More next week when the company demos the Arena at Mobile World Congress in Barcelona.
