Following several reports of Windows Phone 7 devices sporadically transmitting “huge chunks” of seemingly superfluous data via 3G, Microsoft told the BBC that it is investigating the matter. The reports originated on a Windows enthusiast site where a reader claimed her phone was sending a large amount of data unbeknownst to her. She discovered the issue when she received an email alert from AT&T stating that her data usage was nearing its monthly limit. Several other Windows Phone 7 users mirrored the claims after examining their own data usage. Upon learning of the apparent bug, Microsoft confirmed that it is working on a fix. “We are investigating this issue to determine the root cause and will update with information and guidance as it becomes available,” a Microsoft spokesperson told the BBC.
