I am a big fan of ringtones, I download every type of ringtones which suite 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. If anyone has idea about why this problem is occurring then please help me out. I urgently need free ringtones for my boost mobile.
