Confused a little here, and this is probably because I've used an iPhone and BlackBerry for so long. Anyway... If I switch my Samsung Infuse to the vibrate\silent mode, when calls, emails, text, tweets, facebook, google+, and other items come through, shouldn't it vibrate? I've noticed that in some apps, like twitter, and facebook, there are options to turn on vibrate. BUT, if I do this, and the device is set to 'sound', then it tends to vibrate, too when a new notification comes in for that application. Bottom line is, I want when the device is set to silent\vibrate ALL notifications come through as a vibrate. But, if I have the device set to 'sound', ALL notifications come through as sound. Does that make sense? And thus how can I achieve this?
