You probably already know how to customize ring tones on your iPhone, but there’s a way to personalize vibrations to tell who’s calling, too.

With a few setting adjustments, it’s easy to set up customized vibration so you can know when mom’s calling when your phone is on the other side of the room.

This is one of my favorite tips to show to those unfamiliar with the ins and outs of the iPhone’s OS. It’s really helpful because you can set customized vibrations so you don’t even need to look at the screen or hear the ringer to know who’s calling.
