If Microsoft had sold 5 million Windows Phone 7 devices, or even 1 million, you can bet Microsoft would reveal those numbers without being prompted. Instead, the company isn’t releasing any sales figures, which is certainly a marked difference from Apple’s Steve Jobs’ public statements about iPhone and iPad sales.

AT&T gave me a statement that was almost identical to the one Microsoft provided. “While we don’t disclose specific sales figures, we’re encouraged by the demand from customers in stores and online,” AT&T said. T-Mobile offered a little more specificity, saying that while an Android phone was its biggest seller on Black Friday, “our new Windows Phone 7 offering, HTC HD7, is also among our customers’ top smartphone choices.”
