Just a week back i bought coolpad s100. No doubt for a touchscreen phone it is a reasonable price. I was told by reliance store executive to insert 1gb micro sd card but whereas in the instruction book it is just sd card. I am now in a confused state. Secondly, the instruction is not elaborate and not to the point and there are no pictorial instruction and this annoys me very much. If you take instruction books of japanese, korean or usa,one will find step by step instruction so that a novice can learn and operate and that is the purpose of the book but here it is complete bull****.
