Don’t know what to do with all these Windows Phone’s? Microsoft is running a promo for future WinPho7 purchasers in the US that will give them a 3-month Zune pass. All you need is an email and pre-order a Windows Phone.

According to 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.
