Vodafone has wheeled its first co-branded McLaren Mercedes handsets out of the shed and onto the starting grid. Lining up to take on all challengers is a trio of handsets: Samsung's Z720M slider and two clamshells from Sharp, the GX29 and 770SH. The 720M's key features are a three megapixel camera with autofocus; 3G connectivity with HSDPA; Bluetooth 2.0; and a 1.9in, 240 x 320 display. The GX29's a much more basic, VGA camera model, while the 770SH is a 3G device that sits between the other two. ®
