It is quite obvious that sleek looks and youthful appeal are very high on the LG list of priorities recently. Just as we gave you the flamboyant LG KF600, LG KF510 makes us wonder how much sweeter Chocolate can get. Undoubtedly of the same bloodline, the two handsets take a different approach to full touch navigation with InteractPad and Touch Lighting. The rest of the ammo is basically the same. The really sleek metallic finish and bigger 2.2" display (no InteractPad to shrink the screen) are the LG KF510 major assets. The ultra slim slider has the looks and handling to get us exited.
