The news just keeps on coming today for Windows Mobile enthusiasts. This morning, Microsoft announced that “Windows Phones” — aka handsets powered by Microsoft’s Windows Mobile 6.5 OS — would begin to reach market on October 6th. Now, AT&T has jumped in to reveal plans to add Windows Mobile-powered handsets to its free Wi-Fi pool. That’s right folks, starting Friday September 14th, AT&T’s WinMo smartphones will gain free access to each and every AT&T Wi-Fi hotspot. BlackBerrys and iPhones have enjoyed free AT&T Wi-Fi for quite a while now, so it’s nice to finally see Windows Mobile join the fun. There are two requirements of course, the first being an unlimited data plan or other qualifying data option. Secondly, your WinMo handset must, in fact, have Wi-Fi capabilities in order for you to enjoy free Wi-Fi. Right on.
