I read a couple of reports from Engadget and the BBC that some Windows Phone 7 devices seem to be consuming data at an extraordinary rate. I have been using Windows Phone 7 devices since last July and find this reported anomaly hasn't affected me with the HTC HD7 or Samsung test WP7 device.
Matt Miller over at ZDNET has been looking into the reports of rogue data usage by Windows Phone 7. He has had zero issues while using both the HD7 and the Samsung Taylor on the T-Mobile 3G network. I have also been using the HD7 on T-Mobile and have had zero issues with data, so this could be isolated to AT&T. Have any of our readers encountered any issues with extreme data usage? Microsoft is investigating the issue but whether this is an AT&T issue or caused by a rogue app only time will tell.
