Is there a way to customize vibrate patterns?
I want a custom vibration "tone" (pattern) for different callers or applications.
Does Android have any facility for this? Can contacts hold custom information like this?
Using the app, Locale, you can use the Contact condition to spot the caller and the Notification plugin action to use a vibration pattern.
There does not appear to be a contact-specific configuration built-in, even in Froyo.
