Mobile World Congress - New UI revealed

There have been a couple of Android prototypes shown so far in the first day of the Mobile World Congress at Barcelona. Gizmodo has a hands on video with the very familiar low end Android prototype that we've seen a few times already. Engadget is showing off some pics of the same prototype and of a NEC development board that sports a much different UI than the one we've seen in the SDK.

So far none of these phones look like real phones that will be headed our way. Hopefully we'll see something from HTC or another manufacturer this week. We'll keep you updated!

Update: Google's Dan Morrill has revealed that the pics of the NEC demo is the new UI promised in the next SDK. Reuters also has some pics of the new UI.
