Ah Bing Rewards, one of the great and unheralded features of Microsofts search engine, how you tease us so. We’ve just received an E-mail introducing a new sweepstakes being run through Bing Rewards that gives Rewards members the opportunity to trade in points for entries to win one of 5 Windows phone 8X by HTC.

It’s a relatively straightforward sweepstakes, all you need to do is be a member of the Bing Rewards program (which is free) and have enough points to submit an entry into the sweepstakes. Microsoft is footing the entire bill on the phone and giving it to you for the carrier of your choice, along with a $200 check to help pay your initial service expenses. This is a pretty good opportunity to get your hands on the newest member of the Windows Phone 8 family and you won’t have to worry about it not working with your current provider.

There are a few other neat things going on with Bing Rewards lately as well, like the ability to trade in rewards points for Windows Phone gift cards that can be used to purchase Apps. But the real deal here is the sweepstakes, so get registered and get those entries in!
