Hello! I recently bought a Sony Ericsson W550i Walkman and it is a great phone and very very appropriately priced. However, the most major drawback that it has is that it does not support expandable memory. Therefore, I want to make good use of the 256 MB provided. Can you guys please suggest a good method of reducing the size of MP3s? And how much quality will be lost in the process, if any? Thanks!
