NO Winamp. But possibly you can install KD Player and Xploreme (google for these java apps) which haf media players. But my advice is to stick with the default one as its the best!
Forget about winamp flash lite does not come pre installed as they have said in their website. Flash required to locate a store next to you on nokia.co.in
