Here are leaked shots if Sony Ericsson G705 slider mobile phone, the future successor of the G700. The G705 will feature a 2.4-inch LCD screen, a 3.2 Megapixel camera, integrated GPS support, 128MB built-in memory and probably a Memory Stick slot. The phone will run the A2 OS platform.
As seen in the pictures, the Sony Ericsson G705 has a front camera. I guess it should supports 3G or 3.5G HSDPA and the camera is for video calls.
