Staring immediately and lasting until “Supplies last”, when you buy any Windows Phone from AT&T you’ll not only get the only OS with “Xbox Live and thousands of apps”, but 3 months of Zune Pass at no additional charge.
To get your free 3 months buy a phone from AT&T and go to freezunemusicnow.com and follow the steps.
While the Windows Phone update pretty much killed any remote chance AT&T might have ever had of getting us to sign a contract with with them, I can’t deny that getting 3 months of Zune Pass wouldn’t have made our carrier decision a little more difficult back in January.
