Did LinkedIn use PhoneGap or Trigger.IO for its iPhone app?

backbone.js, cordova, javascript, linkedin-api, trigger.io

Solution

Actually they used websockets to communicate from the JavaScript to native layer.

Problem

I keep reading all these articles how LinkedIn used node.js and backbone.js to build their mobile application. See this article: http://venturebeat.com/2011/08/16/linkedin-node/ In it they say LinkedIn used only 5% native phone features. The other 95% was cross-platform HTML, JS, and CSS. What I don't see in the article is any mention of PhoneGap or trigger.io. So how was linkedin able to make their mobile application with just javascript and access "5%" of the native api's? Thanks!
