If yesterdays series of Windows Phone 7 announcements has got your mouth watering and you have decided to pre-order one for yourself, Mobile Crunch has clued us in on a pretty sweet deal that you can't pass up. If you pre-order a Windows Phone 7 device and are not already a member of the Zune network, you get a three month Zune Pass with your order.

What a three month pass to the Zune Marketplace will entitle is unlimited streaming and downloading of songs to your phone, PC, and Xbox 360 for three months, and within those months, you will get to "keep" ten songs per month. If you're already getting a WP7 device, why not? It will save you $14.99 per month, for a total savings of $45 which isn't too shabby. Unfortunately, if you're not in the United States, this offer is not valid.

Here's the message straight from Microsoft:

"Sign-up to be notified to pre-order the new Windows Phone, and we’ll give you unlimited music for 3 months with a Zune Pass—FREE*. Just give us your email address. When Windows Phone is ready to pre-order, use the same e-mail address you sent to us, and when your Windows Phone ships, we’ll send you a 3-month Zune Pass, free."
