I am a big fan of ringtones, I download every type of ringtones which suites my mobile. I recently bought a boost mobile it is great and also works quite well. But there is one problem while playing ringtones on it, it says file format not supported. I have many mobiles and there is no such problem in any of them. I think it supports metropcs. If anyone has idea about why this problem is occurring than please help me out. I urgently need free ringtones for my boost mobile.
