Earlier today Google teased us with an announcement of a “surprise” coming later today. Some speculated the tweet was simply an announcement that the Sprint/Google Voice integration had been completed.

A few hours passed and they announced Android Gingerbread 2.3.4 was being released, bringing bug fixes to the Nexus One and audio/video chat to the Nexus S. This, however, wasn’t the “surprise” they’d mentioned in their tweets.

The big “surprise” turns out to be a “Twitter Puzzle contest” which will give participants ten chances to win a Nexus S.

“To enter the Contest, visit the Google Nexus Twitter page, twitter.com/googlenexus (“Contest Site”) during the Contest Period and review the essay question or puzzle of the day. To submit to a Solution, you should reply to the Google Nexus puzzle, photo or essay question tweet, and you must include the #googlenexus reference. Where applicable, the Solution must meet the “Solution Requirements” …”

So while it was nothing breathtaking, it’s still a fun way to get people interested in the Nexus S.
