• Answer to: Why iPhone 4 doesn't vibrate?

    I was having an issue where my phone was not vibrating for incoming calls even though it was set to vibrate in silent mode. It was still vibrating for texts. I finally figured the solution that worked for me: Settings > Notifications Center > Phone (Badges, Alerts) > Alert Sound > Vibration; make sure it is set to anything but 'NONE' to receive vibration. Same works for texts just follow the same steps as except select Messages instead of Phone so its: Settings > Notifications Center > Messages > Alert Sound > Vibration set to anything but NONE
