Head over to Bing Rewards and enter to win a Nokia Lumia 900. It also comes with $200 cash to cover the some of AT&T service contract. The contest ends May 1st. Winners will be randomly selected on or around May 10, 2012.

One entry will cost you 10 Bing Rewards credits. I’m not sure how, but I already had 24 credits in my account. I entered twice with my points and plan to enter again after gathering more credits.

You can earn Bing credits by referring friends, searching on Bing, or other simple tasks such as following the @BingRewards twitter account.
