setup a new alarm tone

i am using n73. How can I enter new mp3 to alarm tone? Please help me.

I'm afraid you have to use native Symbian API.

Don't be afraid. We are straightly taking people without any gossip. Thats why i asked that question in that way. Anyway can you tell me the meaning of native symbian API, is that an application?
