Hey guys

I am developing an application and I want to change the default ringtone into my own ringtone from my own program.I have heard that I can do so by changing the profile by reverse engineering profileengine.lib.But the problem is I don't know how to reverse engineer that library file and I can't find that library file in my Symbian 7.0 SDK .Therefore I would be very grateful if you can give me some information regarding changing the user profile.I would also be very happy if you can give me information about where I can get the profile engine.lib file.

I look forward to hearing from you soon.

Thanks in advance.
