PhoneTree for Windows Phone 7 has won a netbook in the Twilio Netbook Contest, with its creator Barranger having successfully built the application using Silverlight, XNA, and the Twilio API. The idea for PhoneTree came from a personal experience, while the use of Twilio simplified the development process due to its simple API and compatibility with existing WP7 apps. Integrating Twilio with chosen tools and technologies was straightforward, thanks to open-source projects like the TwilioApi project. Barranger's experience with developing with Twilio began after hearing about it through the contest, where he leveraged his prior knowledge of WP7 apps to successfully integrate Twilio into PhoneTree.
