This is a little expensive ~

Sony Ericsson K790c is not listed, and it costs about 4,500 yuan.

Advantages: Classic Sony Ericsson design, comparable to the camera of card machine, rich data transmission support.

Comments: As the flagship image product of Sony Ericsson in 2006, K790c has powerful entertainment configurations such as 3.2 megapixel camera, auto focus, xenon flash, and new BestPic function. With the classic modeling of Sony Ericsson, this machine is bound to be very popular.
