low end light weight mobile

Hi Friends,

I m looking for low end light weight mobile. My priorities are:

1. Light weight - means less then 100gm is must.

2. Atleast 2g but 3 G is added advantage.must have email facility.

3. Having twitter app is good.

4. not interested in touchscreen phone. qwerty is fine.dual sim or single sim is not an issue.

5. have good battery life.

mostly required this phone while travelling. so from Nokia i think is good. open to other brands as well. but not chinese copies.

budget - 2k - 5k max.

Thanks
