IOS7 was released (Yesterday?). Due to the large number of IOS devices out 
in the world. Some network operators experienced large spikes in traffic as 
each device was updated (Downloading the update). You see the same thing 
happen when new software is released from people like Microsoft. Or, If 
you're a gamer. When a new game is released on a digitally delivered 
platform like Steam or EA's Origin.

Can someone please explain to a non-Apple person what the hell happened 
that started generating so much traffic? Perhaps I missed it in this 
thread, but I would be curious to know what iOS 7 implemented that 
caused this...

Thanks in adavnce,
