Hey people,I am thinking of purchasing a new cellphone. My budget is ~9000INR. I want it as feature rich as possible. Let me know which one is good. I really loved the SE w550/600 but it doesnt have expandable memory. Any phone which has its features and an expandable memory is good for me. BTW what is the difference between the w550 and w600??All suggestions are welcome! BTW my budget is flexible by Rs.1000 😛
