Window 7 Phone to launch 10/11 with either T-Mobile or AT&T or both

Finally we have an official launch date for the Windows 7 Phone, Microsoft’s long-awaited and arguably incredibly tardy entry into the smart phone market. While the WSJ and others were reporting as late as Friday that it would be carried exclusively by AT&T, but the reality looks a little more complicated than that. We know that T-Mobile reps will be at the launch event. We also know that Ralph De La Vega, CEO of AT&T’s mobile division will be there. So one would posit that the phone would be available on both carriers. Will there be a T-Mobile version? I don’t know. But we know the phone’s launching next Monday.
