Phonegap iOS vibration duration workaround

Question

Does anyone know how to create longer than usual vibrations for iOS in Phonegap?

The docs explicitly state:

navigator.notification.vibrate(2500);
IOS: Ignores the specified time and vibrates for a pre-set amount of time.

I would really like to know how to get around this. It's kind of a deal-breaker.

I've been struggling with this too last week. I doubt there is a way to modify the default vibration duration in Phonegap as there is no way to achieve this with the iOS API. The default vibration:

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)

lasts 4 milliseconds with one millisecond of silence. You can try to chain the same method several times but there will be always an interruption between two calls. I think there is no way to make a lengthy vibration that lasts more than 4 milliseconds :(
