Can someone help me please because I have jailbroken my ipad 4.2.1 and when I went to change my new-mail.caf like I have for my iphone and ipod touch it isn't working. It's not playing the sound no matter what I do. I don't know if this is something people know about already or if there is something I'm doing wrong. I used the same .caf file that I used for all the other devices so I'm wondering is there a new way it needs to be done now. Thanks for any and all help that you can provide me.
