Twilio SMS is being used by hackers to interact with Siri, allowing them to send SMS to their apps using the virtual assistant's voice-based interface. To encourage more developers to explore this capability, Twilio is hosting a contest where participants can submit videos showcasing creative uses of Siri and Twilio. The contest, which runs until November 13th, offers a grand prize of a Kindle Fire for the best video submission, as well as bonus points for submissions to the Twilio App Gallery and use of the Twilio Client. The contest aims to encourage developers to build innovative applications using Twilio's cloud communication platform.
