iPhone 4, Push Notifications At Night Time, Any Way to Stop?

I'm wanting to know if there's a way to stop push notifications, or at least stop their sound during nighttime?

I don't want to silence the phone, becau开发者_StackOverflowse I need the alarm to sound in the morning. It'd be nice if I could specify that push notifications should only come through between certain hours, or be quiet during the night...

Thanks.

I believe alarms will still sound when the switch is set to vibrate. Otherwise, what good would they be?

Alarms do sound when the vibrate switch is on. I switch mine off all the time for that same reason and still get up in the morning

Jailbreak your phone, and install one of these apps:

Auto Silent: http://iphonepackers.info/

SBSchedule: http://tom.zickel.org/iphone/cydia/sbschedule/depiction/

This question is now redundant as iOS now has Do Not Disturb mode that can be scheduled.
