I happened to catch the second clue in the Google Nexus (@googlenexus) Nexus S contest about 20 minutes or so after they posted it. I didn't get the first puzzle; I thought I did but I was wrong. This one I was on the right track right away. The clue was:
Puzzle Challenge #2: There is more than meets the eye at http://goo.gl/MKoc8. You'll find the answer in a tweet.
So the first thing I did when I went to the page was look at the source code. At the very bottom of the page I found this:

I noticed the binary around the android's belly so I translated it into ASCII text and got the following URL: http://goo.gl/jPOIl.
I went to the URL and was faced with a puzzle with a timer. The puzzle involved rearranging letters, by swapping two neighbors, in a string
so they were in the "correct" order. You could see how many were correct at the bottom of the page. It was pretty simple and I got the solution before the timer ran out (it took me a few seconds to recognize I was being timed).
Clicking the Tweet your victory! button opened a web tweet box with the message:
@googlenexus Run, run, as fast as you can! You can't catch me, I'm the Gingerbread Android!
I hope it's not against the rules to post the solution; I looked quickly through the legalese and didn't see anything forbidding it.
