My sister and I bought LG A258 for our mother.
It costs 2090 THB. It is quite hard to find a review or a demo. However we bought it :-P.
It is quite a good phone, Basically its screen and keypad are quite large. It also comes with Facebook client, camera, a small screen on its shell, web browser etc. Its UI is quite responsive (at least when we compare it to LG GS108).
I guess using it will be enjoyable.
However IMO it is not for hard-core social network service users.
