LG's U400 3G slider for music

It looks like LG and Hutchison 3 had another ace up their sleeve this week, announcing the U400 slider alongside the lower-end U300 clamshell. The glossy black finish of the U400 is vaguely reminiscent of LG's Chocolate, but the similarities end there: the U400 is thicker, packs UMTS, and trades the Chocolate's hidden music controls for an honest-to-goodness scroll wheel. Other features include A2DP support, 2 megapixel shooter, and MicroSD slot -- but if this is a Hutchison 3 exclusive like the U300, most of us'll have to get our 3G scroll wheelin' kicks vicariously.
