Ok so I have an iPhone 4,& all of a sudden JUST the alert tones r busted,(I.e. messages tones,lock sounds,keyboard clicks). No my phone isn't on silent,my ringer volume isn't turned down,I recently installed sireet and I have removed that,still nothing. I've rebooted,resprung,and done hard resets many times. So any other helpful ideas that don't involve restoring?
