This is fitting here, but I guess this could also be in the iOS6 section of the forum. It hasn't been discussed, but this feature, just like the retina display MacBook Pro is POWER NAP. Although it would be done differently. I would assume it's possible to implement easily into iOS and being as the iPhone is the new gotta have, Apple would make it exclusive to it's new device. For those who don't know what POWER NAP is: It was Apple's "power-saving" option that allowed updates and mail and messages to be fetched and updated automatically. Sure the phone is on standby and we have push notification, but wouldn't it be interesting to implement POWER NAP as part of the DO NOT DISTURB feature being touted by Apple in iOS6. Just a thought.
