So here's the story -- supposedly an anonymous fellow purchased a Nexus S on eBay, and to his surprise found it running Ice Cream Sandwich. There are quite a few visual differences, namely a new launcher style, a new "Google Apps" folder, a new notification bar, and a new lockscreen. There's also what looks to be a panorama feature in the camera, and the "Movie Studio" icon in the app drawer. Everything is nice and fluid -- at least everything we get to see.
Here's where things get sticky -- those things can all be (and have been) faked. Would it be easy? Hell, no, but it's entirely possible. With ICS coming sometime soon, this very well could be a development unit that somehow slipped away from Mountain View -- we've been expecting a leak or two for a while now. But we have to hold off judgement and will let you guys decide and discuss yourselves. Be sure to hit the source link and check out the video after the break if you haven't already.
Thanks everyone who sent this in!
