We first saw AT&T offering a free Zune pass back when Windows Phone first launched--anyone remember the "free entertainment pack"? It now looks like they are returning to a similar offer, along with Amazon Wireless, for a limited time (through June 26th) but instead of one 30-day pass, they are offering three-full months.

Valued at about $45, it's not a huge offering but lets not kid ourselves: the Zune Pass is one of the best things Windows Phone has going for it and something the competition is lacking (although Apple is making strides in this area and Google/Android is working closely with Amazon).

Your three-month Zune Pass ($44.97 value) gives you: unlimited access to over 11 million songs to stream or download; access to music on your Windows Phone 7, Xbox console or PC; and 10 free songs per month to download and keep forever (30 Songs total)

We doubt this is a make-or-break deal for potential new customers, but it sure sweetens the pot, especially since the much coveted and praised Samsung Focus goes for $49.99 at AT&T or the low-low $0.01 at Amazon Wireless. Head over to http://www.freezunemusicnow.com/ to get your Zune code.
