Hi, new poster here with a problem. I have bought ToneFx Pro through Cydia, and although i can use my own tones within it, i cannot, repeat cannot replace the "unlock" sound that came on the iPhone4, with one of my own ringtones. Every other sound can be switched, except that one. I've e-mailed the Dev, but haven't gotten any replies. If anyone could help me, i would greatly appreciate it. Thanks.
