The new Windows Phone 7 devices are headed to AT&T and to help sweeten the deal, AT&T is offering a free entertainment pack for a limited time.

The entertainment pack includes the XBox Live puzzle-game "Ilomilo", a 30 Day Zune Pass, and a free month of AT&T U-Verse Mobile. The $29.95 valued freebie will be available to AT&T customers who purchase a Windows Phone between October 25, 2010 and December 31, 2010.

You can find all the fine print on the offer over at AT&T's website.
