Tech industry pundit Michael Gartenberg (via Twitter) is hearing from a trusted source that AT&T has signed up for 8 million devices powered by Windows Phone 7. HTC, Samsung are likely. Given the nature of a 140 character tweet, no information was given on timeframe. It could be 8 million for launch or 8 million for the first year. Still, it’s clear that AT&T is committed to Windows Phone 7 in a big way. Now it’s up to the manufacturers, Microsoft included, to deliver phones that leave those shelves at AT&T. Full context of his tweet below.
It should be noted that Gartenberg isn’t one for rumors, so expect a big Windows Phone 7 splash at AT&T this holiday season.
