Good Vibrations

Problem: You would like to know who's calling you without having to take your phone out of your pocket or purse, while your phone is in silent mode (ringer turned off).

Solution: Create unique vibration patterns and assign them to people you know.

To create a new vibration pattern,

1) Go to

    Settings > Sounds > Ringtone > Vibration > Create New Vibration

2) Now start tapping a beat on the gray area
3) Tap on the Stop button
4) Tap on the Save button
5) Specify a name for your vibration pattern

To assign a vibration pattern to a contact,

1) Launch the Phone app
2) Tap on the Contacts toolbar icon (on bottom of page)
3) Tap on the Edit button
4) Tap on Vibration
5) Select a vibration from the list (the custom ones are at the bottom)
