Christopher Mims highlights a neat new feature in iOS 7:
Multi-path TCP allows your phone to send data by whatever way it’s connected to the internet, whether that’s Wi-Fi, 3G or ethernet (say, if it were running on a laptop connected to the internet via a cable). And if you want to activate it, says one of the researchers who built multi-path TCP, you have only to use Apple’s voice command software, Siri.
This is the first time that this new means of connecting to the internet has appeared in a commercial product. That it showed up in Apple’s software and not Google’s shows that Apple’s technical chops are substantial, even when the company isn’t highlighting what it’s up to.
