Unpacking rar on iPhone

Question

I created little download application with music player and now I want it to unpack archives, because quite often mp3s are packed in archive and you can play them before you unpack the archive. I found solution for .zip files on iPhone here on stackoverflow, but I'm wondering if there's a way to unpack .rar files, or other than .zip formats.. Many times, I red about creating own utility to do this, but I don't know whether I am able to create it or not. Could you please tell me if there's any solution for unpacking .rar(or simply other than .zip) archives on iPhone? Thanks

UnRar has source code included, so if all fails, you could have a look if there is a port for the iPhone or try to do this yourself. For Symbian Phones, there seems to be FreeUnRar.
