As with the release of all the past Nexus devices, Google is gearing up to give away 10 Galaxy Nexus phones over the next 10 day. In the past, the contests have been a mix of riddles, math equations, even source code or food challenges. We’re not sure what to expect from this round of giveaways, but we know everyone will want to get their hands on one of ten Galaxy Nexus devices. The contest starts tomorrow Nov 12th at 9am PST, so make sure you’re following @googlenexus on Twitter or you have Android in your circles on Google+.
