By brolloh With so many notifications coming in from so many apps and people, it can be hard work looking at your phone every five minutes only to see that you’ve had yet another pointless email come through.
iOS 5 and iOS 6 feature custom vibrations so your important contacts stop getting lost amongst the rest.
To create this new vibration, navigate to Settings > Sounds > Select your current ringtone > Vibration

You’ll be given a list of seven default vibration patterns. Scroll beyond the bottom of this list and you’ll see ‘Create New Vibration’

You’ll be presented with a large grey square to tap on, this will record the vibration you have in mind. (Quick tip: simplicity is the key but who are we to judge?)

When you’re finished, you can tap Save and name your masterpiece.
Now navigate to your Contacts app, find your loved one, tap Edit, just under E-mail you’ll see Vibration: Default, tap this.

Scroll to the bottom and select your custom vibration.

Now you know who calls or iMessages you before you see it.
More soon!
