I was messing around with my IPhone today and was on my Xbox Live app and noticed this new feature. It has been on there for a few days I believe but I had to check it out. The new Quickplay feature allows you to connect and control certain things on your Xbox via your phone.
It seems like it is a little peek of what to come with the new SmartGlass feature yet to release. I took a couple of screen shots to show you what it looks like. Basically you can select recent activity that you had on your Xbox and select it from your phone. Once its loaded on the Xbox you have this generic controller that works just like your normal controller. Great for Netflix and even can use on a game though a very slight lag is present.
Let me know if you have used it and tell me what you think about it.
