Vibrafications:Jailbreak app

Vibrafications is a tweak that allows you to set custom vibration patterns to different alerts. You can set a custom pattern for individual contacts in mail or sms, or you can set a default pattern for mail and sms in general, and you can define custom patterns for push notifications, or a default one for all push notifications. Patterns include things like vibrate three times for half a second each with a quarter second in between each vibration. No new icons are added to your home screen. Options can be configured in your Settings app.
