I've installed Sendsong, and got it working to put custom ringtones in the Sounds>Ringtone>Custom list, but none of them will work. In fact none of the stock ringtones work anymore either, and so my iPhone is currently vibrate only to let me know I've got an incoming call. Sounds are working as I can preview ringtones (not custom ones) and ipod function works. Curiously keyboard clicks and lock sounds are now not working either. Has anybody got any ideas how I can fix this? Would be much appreciated if you had any ideas.
