Links: Hands-on with LG GT540 LG Optimus GT540 Review

LG Optimus GT540 is LG's second Android phone. It attracts the attention with its design – with very round edges and metal like trim around the corners. The controls are a combination of two touch sensitive buttons (back and menu), while the home, call and end are regular ones. Specs-wise, there is not a lot to talk about – 3 mega-pixel camera, video player with DivX support and microSDHC card slot.
