How to get the user's device information of a tweet via Streaming API?

[Peorthrind]

I’m interested in the different twitter user’s behavior among mobile devices or operating systems(i.e iOS, Android…).

So I’m wondering how to get the device information of a tweet.
I’ve read the “A field guide to Twitter Platform objects”, and I didn’t find the “device” or “operating system” information I want.

Is there such a thing in the informations which could be gotten from Streaming API ?
Did I miss something?

Thanks.

Peorthrind, the device and operating system are not available from the Twitter API. However, the source attribute of a Tweet can tell you about the name and URL of the application used to post the Tweet.
