Chrome on Android?
- 
 I used an app from OpenStore to access Twitter, that being Tweet Mobile, and I received an email from Twitter that identified my device as "Chrome on Android". Chrome? On Android?

 It's easier to mimic Chrome on Android than to try to get websites to recognize your custom user-agent and provide the correct website.

 @UniSuperBox, Makes sense. I recall some years ago when I was using Firefox, or maybe Mozilla Suite (it was a while ago, before Mozilla/Firefox were recognized identities), I sometimes had to change the identity of the browser to IE to be able to fill out online forms. The identity was somewhere in the Tools/Web Developer options (though I don't currently see anything like this in Firefox).
