ok i looked around here trying to find answers no luck yet so ill create my own thread.
on my storm when i go in and change a sound profile i normally only use the normal and the vibrate profile now when i go in and set a custom tone for messages it will ring that tone then when i get to work change my profile to vibrate and that same person sends me a txt it still rings as though the profile is on normal but its on vibrate.
Best thing to do is set up your own custom "Vibrate" sound profile, and then set your phone to that when you want it to vibrate (instead of the vibrate sound profile that came on the phone). Using your own custom sound profile will override the custom ringtones you have set for your contacts. This is the work around for the .75 OS bug.
