As the name suggests, the app is a simple package that increases the vibration time when you receive a new message. The iPhone’s vibrator isn’t all that good and therefore many a times you do not realize that you have received a sms. Even its speakers volume is low so again there is a problem. So Extra Long Vibration is our solution. This package via Cydia is not an app, nor it is a toggle. You simply have to install it, and it gets activated. However, to disable it, you will need to go manually to Cydia and delete it.
All in all a great tweak for the iPhone and works well!!
Note: Works only on jailbroken iPhone firmware 3.0
