A feature I would love to see in iOS 6 or the new iPhone is when your phone is off or dead, once it's powered back on, you get a notification that someone has tried to call during the time that it was off. Who's with me?
^ This. The OS and apps can only do so much.This is most likely a limitation of the network and not the phone.
Me too.I usually get a text from my carrier notifying me who tried to call me if my phone was off or not in a service zone
