Like many people my phone is most of the time in silent/vibrate mode. I was wondering if there's a way to assign different vibration patterns for different notifications, just like we do for ringtones and alerts with sounds. Maybe there's an app that allows us to do that? I couldn't find anything yet.

I have an HTC Droid Incredible running Android 2.2 FroYo and would like to use custom sounds/songs as ringtones for text message notifications, event and task reminders, Facebook and Twitter notifications, and email messages. I have the MP3s that I want to use located in the /ringtones directory of my phone, but they don't show up on the list of possible sound effects/tones/notifications, but they do show up in the selection for incoming call ringtones. What do I do to …

My current phone is an HTC Desire and I was using an iPhone before. I am really liking the ringtons and other system sounds on the iPhone and I am now looking a way to have these on my Android phone. Are there any apps for that?

I'm running Android 2.2 FroYo on an HTC Droid Incredible. When I go to bed, I want to turn off all notifications except for incoming phone calls, which I still want to receive. Is this possible, either natively or through an application?
